Ministry of Construction Notification No. 1433, May 31, 2000, "Determining the calculation method, etc., for the Fire Resistance Performance Verification Method"

BIM (Building Information Modeling) is used to create 3D models of structures on a computer. However, because there is no data link between the 3D model of the structure (e.g., the BIM model) and the calculation procedures for the verification method specified in the notice, there is a risk of inconsistencies occurring due to input errors or oversights between calculations based on the fire resistance performance verification method and the 3D model of the structure, and it takes time and effort to confirm consistency between the two.

The present invention aims to reduce the work required for performance verification and improve reliability by linking a three-dimensional model of a structure with the data used in performance verification of the structure.

To achieve this object, the first invention of the present invention is a performance verification method comprising the steps of: a three-dimensional model setting step of causing a computer constituting a three-dimensional model system to set a three-dimensional model of a structure having a space composed of components; an extraction step of causing a computer constituting a performance verification system to extract data indicating conditions related to the space or the components from the three-dimensional model; and a calculation step of causing the computer constituting the performance verification system to input the data extracted in the extraction step into a pre-prepared conditional equation using a calculation program for verifying the performance of the structure, and performing calculations, wherein the calculation program causes the computer constituting the performance verification system to calculate the fire duration of the structure .
In addition, in order to achieve this object, the second present invention is a performance verification method comprising the steps of: a three-dimensional model setting step of causing a computer constituting a three-dimensional model system to set a three-dimensional model of a structure having a space constituted by components; an extraction step of causing a computer constituting a performance verification system to extract data indicating conditions related to the space or the components from the three-dimensional model; and a calculation step of causing the computer constituting the performance verification system to input the data extracted in the extraction step into a pre-prepared conditional equation using a calculation program for verifying the performance of the structure, and performing calculations, wherein the calculation program causes the computer constituting the performance verification system to calculate the fire retention fire resistance time of the structure.
In order to achieve the above object, the third invention of the present invention is a performance verification method comprising: a three-dimensional model setting step of causing a computer constituting a three-dimensional model system to set a three-dimensional model of a structure having a space constituted by components; an extraction step of causing a computer constituting a performance verification system to extract data indicating conditions related to the space or the components from the three-dimensional model; and a calculation step of causing the computer constituting the performance verification system to input the data extracted in the extraction step into a pre-prepared conditional equation using a calculation program for verifying the performance of the structure, wherein the calculation program comprises a fire duration calculation program that causes the computer constituting the performance verification system to calculate the fire duration of the structure, and a fire retention fire resistance time calculation program that causes the computer constituting the performance verification system to calculate the fire retention fire resistance time of the structure.

This invention reduces the work required for performance verification and improves reliability.

At least the following points become clear from the description and drawings described below.

A performance verification method has been clarified that includes the following steps: a 3D model setting step of setting a 3D model of a structure having a space composed of components in a 3D model system; an extraction step of extracting data indicating conditions related to the space or the components from the 3D model in a performance verification system; and a calculation step of inputting the data extracted in the extraction step into a pre-prepared conditional equation using a calculation program for verifying the performance of the structure in the performance verification system. This performance verification method links the 3D model of the structure with the data used in performance verification of the structure, thereby reducing the work required for performance verification and improving reliability.

It is desirable to reconfigure the three-dimensional model based on the calculation results from the calculation step. This makes the design work of the structure easier.

The calculation program preferably calculates the fire duration of the structure. It is also preferable that the calculation program calculates the fire retention time of the structure. This reduces the work required to check the consistency between the 3D model data of the structure and the calculation results of the fire duration and fire retention time.

The calculation program preferably includes a fire duration calculation program that calculates the fire duration of the structure, and a fire retention fire resistance time calculation program that calculates the fire retention fire resistance time of the structure. This reduces the work required to check the consistency between the structure's 3D model data and the calculation results of the fire resistance performance verification.

It is desirable that the performance verification system include a determination step for determining whether at least one of the fire duration and the fire retention time is normal. This reduces the work required to confirm consistency between the structure's 3D model data and the determination results.

In the determination step, it is desirable to determine whether the fire-resistance time is equal to or greater than the fire duration. This reduces the work required to confirm consistency between the structure's 3D model data and the determination results.

If it is determined in the determination step that there is an abnormality in the fire duration, it is desirable to identify the room related to that fire duration. Furthermore, if it is determined in the determination step that there is an abnormality in the fire retention fire resistance time, it is desirable to identify the components related to that fire retention fire resistance time. This makes it easier to check whether there is an abnormality in the determination result, and to identify the rooms or components that will result in an abnormal determination result.

It is desirable to use the fire duration calculation program to create a fire duration calculation sheet, and the fire fire resistance calculation program to create a fire fire resistance calculation sheet. This allows for data linkage between the 3D model data of the structure and the calculation sheet, reducing the work required to check consistency between the two.

In the performance verification system, it is desirable to output a drawing created based on the 3D model with information related to the calculation results from the calculation step superimposed on it. This reduces the work required to check the consistency between the 3D model and the calculation results.

After the primary data is extracted from the three-dimensional model in the extraction step, a pre-processing step is performed to convert the primary data into secondary data that can be input into the conditional formula;
After the preprocessing step, it is desirable to use the calculation program to input the primary data and the secondary data into the conditional equations and perform calculations, whereby even if data synonymous with parameters that can be input into the conditional equations is not included in the three-dimensional model data, the preprocessing step can interpolate the data to be input into the conditional equations.

In the preprocessing step, it is desirable to convert the primary data extracted from the three-dimensional model into the secondary data based on a conversion table that associates the primary data with the secondary data. It is also desirable to calculate the secondary data in the preprocessing step by inputting the primary data into a conversion formula prepared in advance. This makes it possible to interpolate the data to be input into the conditional formula in the preprocessing step.

In the extraction step, it is desirable to extract primary data indicating the height, width, web thickness, and flange thickness of the steel material from the three-dimensional model, and in the pre-processing step, to input the primary data indicating the height, width, web thickness, and flange thickness of the steel material into the conversion formula to calculate the heated perimeter of the member, which is the secondary data. This makes it possible to interpolate data on the heated perimeter _Hs required for the condition formula (notification formula).

A performance verification program has been clarified, which comprises causing a performance verification system to execute an extraction step of extracting data indicating conditions related to a space or components from a three-dimensional model of a structure having a space made up of components, and a calculation step of inputting the data extracted in the extraction step into a pre-prepared conditional equation using a calculation program for verifying the performance of the structure. Such a performance verification program links the three-dimensional model of the structure with the data used for performance verification of the structure, thereby reducing the work required for performance verification and improving reliability.

A performance verification system has been revealed that includes an extraction unit that extracts data indicating conditions related to a space or components from a three-dimensional model of a structure having a space composed of components, and a calculation unit that inputs the data extracted by the extraction unit into a pre-prepared conditional equation using a calculation program for verifying the performance of the structure. Such a performance verification system links the three-dimensional model of the structure with the data used for performance verification of the structure, thereby reducing the work required for performance verification and improving reliability.

====Embodiment====
<Overview>
FIG. 1 is a flow chart showing an outline of this embodiment.

In this embodiment, a 3D model setting step is performed first (S1). In this 3D model setting step, a 3D model of a structure having a space made up of components is set in a 3D model system. This 3D model setting step sets a 3D model of the structure in a computer that makes up the 3D model system. The 3D model is 3D data of the structure, such as a BIM model. The structure is, for example, a building, and has a space made up of components. The 3D model describes the 3D shape information (shape data) and attribute information (attribute data) of the structure, and includes data (spatial condition data, component condition data) that indicate conditions related to the space and components of the structure (spatial conditions, component conditions).

Next, an extraction step is performed (S3). In this extraction step, the performance verification system performs a process to extract data indicating spatial or component-related conditions (spatial condition data, component condition data) from the 3D model. In this extraction step, the computer that makes up the performance verification system extracts specified data based on an extraction program, thereby efficiently and reliably collecting data related to spatial conditions and component conditions required for performance verification of the structure.

Next, a calculation step is performed (S5). In this calculation step, a calculation program for verifying the performance of the structure is used to input the data extracted in the extraction step into a pre-prepared conditional equation and perform calculations. This allows data linkage between the 3D shape information (shape data) and attribute information (attribute data) that make up the 3D model of the structure and the calculation procedures for the verification method specified in the notice, thereby reducing the work required to confirm consistency between the two.

In the calculation step, calculations are performed based on the notification formula (corresponding to the conditional formula), for example, using a calculation program for verifying the fire resistance performance of a structure. However, the calculation step is not limited to calculations related to the fire resistance performance verification of a structure, and calculations related to other performance verifications may also be performed. For example, instead of performing calculations for fire resistance performance verification, the calculation step may perform calculations for evacuation safety verification or verification related to normal fires and fire spread prevention.

After the calculation step, the output step is performed (S7). In the output step, the calculation results of the calculation step are output. In the output step, for example, the calculation results are displayed on a display, printed, or saved.

<Main components of the performance verification device>
The performance verification device that realizes the flow shown in FIG. 1 will now be described.
FIG. 2 is an overall explanatory diagram of the performance verification device 100 of this embodiment.

The performance verification device 100 is a system for verifying the performance of a structure (e.g., a building). The performance verification device 100 is composed of one or more computers. Here, the performance verification device 100 performs a fire resistance performance verification of the structure. However, the performance verification device 100 is not limited to performing a fire resistance performance verification of the structure, and may also perform a performance verification other than a fire resistance performance verification (e.g., evacuation safety verification). The performance verification device 100 has a 3D model system 10 and a performance verification system 20.

The 3D model system 10 manages 3D model data of structures (e.g., buildings) that have spaces composed of components. Here, the 3D model system 10 is a BIM model system that manages BIM models 14 (14A, 14B) and is composed of one or more computers. The 3D model system 10 has a data storage unit that stores the BIM models 14 (14A, 14B) and extended data 16 (16A, 16B), and manages the BIM models 14 and extended data 16. Note that while BIM models 14A and 14B are depicted separately in Figure 2, BIM models 14A and 14B are a unified data set (database) as a BIM model. The 3D model system 10 is realized by a processor reading and executing a BIM management program.

BIM model 14 (14A, 14B) is data of a three-dimensional model of a structure having a space composed of components, and is composed of three-dimensional shape information (shape data) and attribute information (attribute data) of the structure. The shape data and attribute data of BIM model 14 (14A, 14B) include data (spatial condition data) indicating the spatial conditions (spatial conditions) required for performance verification, and data (component condition data) indicating the conditions related to components (component conditions). The BIM model 14 is composed of architectural data (design data) and structural data. Extended data 16 is data added and set by the performance verification system 20. Extended data 16 may also be data incorporated into BIM model 14.

The performance verification system 20 is a device that verifies the performance of a structure. Here, the performance verification system 20 is a computer that verifies the fire resistance performance of a structure. The performance verification system 20 is composed of one or more computers. Furthermore, the performance verification system 20 is realized by a processor reading and executing a performance verification program. The performance verification system 20 may be composed of a computer separate from the computer that constitutes the 3D model system 10, or it may be composed of the computer that constitutes the 3D model system 10. For example, the 3D model system 10 may function as the performance verification system 20 by adding (extending) a performance verification program for performing the performance verification processing described below to a BIM management program that manages and controls the 3D model system 10.

In the extraction step, the performance verification system 20 automatically extracts the data necessary for fire resistance performance verification from the BIM model 14. The performance verification system 20 also calculates the information necessary for fire resistance performance verification (specifically, fire duration, fire retention time, etc.) by inputting the extracted data into a conditional equation (notification equation) prepared in advance in the calculation program. This allows data linkage between the 3D shape information (shape data) and attribute information (attribute data) that make up the 3D model of the structure and the calculation procedure of the verification method specified in the notification, thereby reducing the work required to confirm consistency between the two. The performance verification system 20 has a calculation processing unit 30 (30A, 30B).

The calculation processing unit 30 (30A, 30B) extracts data from the BIM model 14 (14A, 14B) and performs the specified calculations for fire resistance performance verification. The calculation processing unit 30 is realized by a processor reading and executing a calculation processing program contained in the performance verification program. The calculation processing unit 30 has an extraction unit 22, a pre-processing unit 23, a calculation unit 24, and a determination unit 25. The extraction step (S3) in Figure 1 is performed by the extraction unit 22. The calculation step (S5) in Figure 1 is performed by the pre-processing unit 23, calculation unit 24, and determination unit 25. The specific processing of each unit of the calculation processing unit 30 will be described later.

The calculation processing unit 30 has a first processing unit 30A and a second processing unit 30B. Here, the first processing unit 30A calculates the indoor fire duration, and the second processing unit 30B calculates the indoor fire fire resistance time. The first processing unit 30A and the second processing unit 30B may be configured on the same computer or on separate computers. The first processing unit 30A and the second processing unit 30B each have an extraction unit 22 (22A, 22B), a preprocessing unit 23 (23A, 23B), a calculation unit 24 (24A, 24B), and a determination unit 25 (25A, 25B). The calculation processing unit 30 may be configured with a single processing unit or three or more processing units. For example, the calculation processing unit 30 may calculate only either the fire duration or the fire fire resistance time, or may have a third processing unit for calculating the outdoor fire fire resistance time.

<Processing of performance verification equipment>
FIG. 3 is a flow diagram of the processing performed by the performance verification device 100.

・BIM model setting step (3D model setting step)
First, a BIM model setting step is performed (S01). The BIM model setting step in FIG. 3 corresponds to the 3D model setting step (S1) in FIG. 1. This BIM model setting step (S01) sets up a BIM model 14 (14A, 14B) in the computer that constitutes the 3D model system 10. The BIM model 14 includes data such as spatial condition data and component condition data. As will be described later, the BIM model 14 may be reset based on the calculation results of fire duration and fire resistance time (indoor fire resistance time, outdoor fire resistance time).

Room Setting Step Next, the room setting step is performed (S02). In the room setting step, the commissioning system 20, for example, displays a setting screen on a display and has an operator input predetermined setting data using an input device (keyboard, mouse, etc.). According to the input setting data, the system sets multiple fire rooms on each floor of the structure (building), sets multiple rooms and room names for each fire room, and assigns ID numbers to each room. The layout of each room in the structure (building) is determined according to the settings in the room setting step. As a result, the walls, floors, ceilings, etc. that make up each room are identified, and data on the spatial conditions (room unique number (ID number), room name (room name), area, ceiling height, etc.) and component conditions (component unique number (ID number), component name (component name), thickness of interior building materials, component type, cross-sectional dimensions, etc.) of the BIM model 14 are associated with each room. The setting data set in the room setting step may be stored, for example, in the extension data 16 or in a data storage unit of the commissioning system 20.

Extraction Step Next, the extraction step is performed (S03). The extraction step (S03) in Fig. 3 corresponds to the extraction step (S3) in Fig. 1.

The extraction unit 22 (22A, 22B; see Figure 2) extracts data of specified parameters from the BIM model 14 (14A, 14B) of the 3D model system 10. The extraction unit 22 is realized by a processor reading and executing an extraction program included in the calculation processing program. The data extracted by the extraction unit 22 includes data such as numerical values and character strings indicating spatial conditions and component conditions. In other words, the extraction unit 22 extracts spatial condition data and component condition data related to performance verification from the shape data and attribute data of the structure included in the BIM model 14. The data extracted by the extraction unit 22 also includes data that can be directly input into the conditional equations (described below) used in calculations by the calculation unit 24 (data equivalent to the various parameters defined in Ministry of Construction Notification No. 1433) and indirect data for calculating the data to be input into the conditional equations. The data extracted by the extraction unit 22 may also include data that is not used in the calculation of the conditional equations by the calculation unit 24. For example, the data extracted by the extraction unit 22 may include data (such as an ID number) used to confirm performance verification. By having the extraction unit 22 use an extraction program to extract specified data from the BIM model 14, data related to the spatial conditions and component conditions required for fire resistance performance verification can be collected efficiently and reliably from the BIM model 14.

The extraction unit 22 extracts a predetermined number of types of data from the BIM model 14 based on a reference table.
4A and 4B are explanatory diagrams of examples of the reference table 42. Each reference table indicates the parameter names of data to be extracted by the extraction unit 22. The reference table 42 is prepared in advance in the extraction program that constitutes the extraction unit 22.

FIG. 4A is an explanatory diagram of a reference table 42A used by the extraction unit 22A of the first processing unit 30A. This reference table 42A shows the data to be extracted by the extraction unit 22A of the first processing unit 30A. The extraction unit 22A of the first processing unit 30A extracts various data related to indoor fire duration from the BIM model 14A based on the reference table 42A shown in FIG. 4A. The extraction unit 22A extracts various data corresponding to each room based on the reference table 42A. Therefore, the extraction unit 22A extracts various data corresponding to each room by correlating it with the ID number of each room. Here, the extraction unit 22A extracts various data such as the room ID number, room name, room use, area (floor area), type of interior building material (non-combustible material, flame-retardant material, etc.), wall core dimensions, and ceiling height from the BIM model 14A in accordance with the reference table 42A shown in FIG. 4A. For example, the extraction unit 22A extracts data (numerical values or character strings) of room names from the BIM model 14A and extracts data (numerical values) of floor areas _Aγ from the BIM model 14A based on the reference table 42A. The data extracted by the extraction unit 22A is mainly data indicating the spatial conditions of rooms.

Figure 4B is an explanatory diagram of a reference table 42B used by the extraction unit 22B of the second processing unit 30B. This reference table 42B indicates the data to be extracted by the extraction unit 22B of the second processing unit 30B. The extraction unit 22B of the second processing unit 30B extracts various data related to the fire resistance time (here, the indoor fire resistance time) from the BIM model 14B based on the reference table 42B shown in Figure 4B. The extraction unit 22B extracts various data corresponding to each component of the structure (e.g., main structural components such as walls, columns, and beams) based on the reference table.

As shown in FIG. 4B, the reference table 42B includes a common reference table 421 (top table in FIG. 4B) and a component-specific reference table 422 (bottom table in FIG. 4B) corresponding to the type of component. Here, the extraction unit 22B of the second processing unit 30B first extracts data such as component ID numbers, component names, and component types from the BIM model 14B in accordance with the common reference table 421. Next, the extraction unit 22B extracts various data in accordance with the component-specific reference table 422, depending on the data indicating the "component type" extracted based on the common reference table 421. As shown in the component-specific reference table 422 (bottom table in FIG. 4B), the data to be extracted differs depending on whether the component is a bearing wall or a steel column. For example, if the type of a certain component is a steel column, various data corresponding to that component, such as the component's height from the floor, the height (composition) of the steel, the width of the steel, the web thickness, and the flange thickness, are extracted from the BIM model 14B.

・Preprocessing step (calculation step)
As shown in Fig. 3, after the extraction step (S03), a preprocessing step (S04) is performed. The preprocessing step (S04) corresponds to part of the calculation step (S5) in Fig. 1. The preprocessing step (S03) is a preliminary process that is performed as necessary to apply the extracted data to the notification formula (condition formula).

The preprocessing unit 23 (23A, 23B; see Figure 2) converts the primary data extracted by the extraction unit 22 into secondary data. The preprocessing unit 23 is realized by having a processor read and execute a preprocessing program included in the calculation processing program. The preprocessing unit 23 inputs the primary data extracted by the extraction unit 22 into the preprocessing program, analyzes the primary data using the preprocessing program, and calculates the data (secondary data) required for the calculation unit 24. Here, the preprocessing unit 23 calculates data that can be input into the conditional equations used in calculations in the calculation unit 24 (data equivalent to the various parameters specified in Ministry of Construction Notification No. 1433). The preprocessing unit 23 interpolates the data of the various parameters required for the notification equations (conditional equations) specified in Ministry of Construction Notification No. 1433 by calculating secondary data based on the data (primary data) extracted from the BIM model 14. This makes it possible to collect data on the various parameters required for the notification formula (conditional formula), even if the BIM model 14 does not contain data synonymous with the various parameters specified in Ministry of Construction Notification No. 1433. However, if the extraction unit 22 can extract all of the data required for calculations in the calculation unit 24 from the BIM model 14, the preprocessing unit 23 may not be necessary.

The preprocessing unit 23 calculates secondary data based on the primary data, using the conversion table.
5A and 5B are explanatory diagrams of an example of the conversion table 43. The conversion table 43 associates secondary data, primary data used to calculate the secondary data, and conversion conditions. The conversion table 43 is prepared in advance in the preprocessing program that constitutes the preprocessing unit 23.

Figure 5A is an explanatory diagram of the conversion table 43A used by the pre-processing unit 23A of the first processing unit 30A. This conversion table 43A shows the relationship between the secondary data calculated by the pre-processing unit 23A of the first processing unit 30A and the primary data. The pre-processing unit 23A of the first processing unit 30A calculates various data (secondary data) related to indoor fire duration based on the conversion table 43A shown in Figure 5A.

For example, the preprocessing unit 23A of the first processing unit 30A calculates the secondary data _ql based on the primary data indicating the parameter "room use" and the conversion table 101 in accordance with the conversion table 43A shown in FIG. 5A. As shown in FIG. 6, the conversion table 101 pre-associates the room use with the value of the secondary data _ql . If the primary data indicating the parameter "room use" is "waiting room," the preprocessing unit 23A calculates "560" as the value of the secondary data _ql . In this way, even if the BIM model 14A of the three-dimensional model system 10 does not contain data synonymous with the parameter _ql (heat generation per square meter of floor area of combustible materials stored in the room) defined in Ministry of Construction Notification No. 1433, the data _ql (secondary data) can be calculated based on the primary data.

Meanwhile, Section 1, Paragraph 2 of Ministry of Construction Notification No. 1433 prescribes the value of "heat generation per square meter of floor area of combustible materials stored in a room _" according to the "room type." However, the "room use" data extracted from the BIM model 14A does not necessarily match the "room type" defined in Ministry of Construction Notification No. 1433. (For example, Section 1, Paragraph 2 of Ministry of Construction Notification No. 1433 includes an item for "conference room and similar" in the "room type" section, but does not include an item for "waiting room.") However, in this embodiment, by pre-setting the conversion table shown in FIG. 6 , when the primary data indicating the parameter "room use" is "waiting room," the numerical data of the parameter _ql (heat generation per square meter of floor area of combustible materials stored in a room) can be set to "160," which corresponds to "conference room and similar."

The method of converting primary data into secondary data is not limited to the method using a conversion table. The preprocessing unit 23 may calculate secondary data from primary data based on a predetermined conversion formula. For example, data (secondary data) indicating the parameter "surface area A _f of each part for each type of interior building material in the room" can be calculated as the product of the wall center dimension (unit: meters) and ceiling height (unit: meters) extracted as primary data (equivalent to conversion formula 003).
Furthermore, the number of primary data used to calculate the secondary data is not limited to one, and multiple data may be used. Furthermore, when calculating certain secondary data, the preprocessing unit 23 may use not only the primary data but also secondary data calculated from the primary data.

FIG. 5B is an explanatory diagram of a conversion table 43B used in the preprocessing unit 23B of the second processing unit 30B. This conversion table 43B shows the relationship between the secondary data calculated by the preprocessing unit 23B of the second processing unit 30B and the primary data. The preprocessing unit 23B of the second processing unit 30B calculates various data (secondary data) related to the indoor fire retention time based on the conversion table 43B shown in FIG. 5B. For example, in accordance with the conversion table 43B shown in FIG. 5B, the preprocessing unit 23B calculates data (secondary data) indicating the parameter "heated perimeter Hs of the member" based on the primary data, namely, the "height H" of the steel material, the "width _B " of the steel material, the "web thickness _t1 ," and the "flange thickness _t2 ," and the conversion formula shown in FIG. 7 (corresponding to conversion formula 201 in FIG. 5B).

Here, data on various parameters required for the notification formula (conditional formula) is collected through the extraction step and preprocessing step. However, in the preprocessing step, the worker may be asked to input data on some of the parameters required for the notification formula (conditional formula), and the input data may be interpolated as secondary data. In this way, even if some of the data is input by the worker, the remaining data is linked to the BIM model 14, reducing input errors in data required for calculating the notification formula (conditional formula). On the other hand, in order to prevent data input errors, it is desirable to collect data on all parameters required for the notification formula (conditional formula) through the extraction step and preprocessing step.

Calculation Step As shown in Fig. 3, after the preprocessing step (S04), a calculation process for the fire duration (S05A) and a calculation process for the fire's fire-resistance time (S05B) are performed. The calculation processes (S05A, S05B) in Fig. 3 correspond to the calculation step (S5) in Fig. 1. Here, the calculation unit 24A of the first processing unit 30A calculates the indoor fire duration (S05A). Furthermore, the calculation unit 24B of the second processing unit 30B calculates the indoor fire's fire-resistance time (S05B).

Calculation unit 24 (24A, 24B; see Figure 2) inputs the primary data extracted by extraction unit 22 and the secondary data calculated by preprocessing unit 23 into a pre-prepared conditional equation (notification equation) and performs calculations. Calculation unit 24 is realized by the processor reading and executing a calculation program contained in the calculation processing program. The calculation programs constituting calculation unit 24 (calculation units 24A, 24B) include a fire duration calculation program that calculates the fire duration of a structure, and a fire retention fire resistance time calculation program that calculates the fire retention fire resistance time of a structure.

In the calculation step (S05A) of FIG. 3 , the calculation unit 24A of the first processing unit 30A calculates the "calorific value _Qγ of the combustible materials in the room" for each room. The calculation unit 24A calculates the "total calorific value Qγ of the combustible materials in the room" by inputting data (primary data) for the parameter "floor area _Aγ " shown in FIG. 4A and data (secondary data) for the parameters ( _ql , _qf , _Af , ...) shown in FIG. 5A into each parameter (variable) of the conditional equation for calculating the "calorific value _Qγ of the combustible materials in the room" defined in Ministry of Construction Notification No. 1433, Part _1. The calculation unit 24A also calculates the "calorific value _qb per second of the combustible materials in the room" for each room. The calculation unit 24A calculates the value of "the amount of heat generated per second q _b from combustible materials in the room" by inputting the values (primary data and secondary data) indicated by the predetermined parameters into each parameter (variable) of the conditional equation for calculating "the amount of heat generated per second q _{b from combustible materials in the room" as defined in Article 2 of Ministry of Construction Notification No. 1433. The calculation unit 24A then calculates the value of "indoor fire duration t f} " by inputting the values of "the amount of heat generated per second Q _γ from combustible materials in the room" and "the amount of heat generated per second q _b from combustible materials in the room" for each room into the conditional equation (t _f = Q _γ /60q _b ) defined in Article 108-3, _{Paragraph 2} of the Enforcement Order of the Building Standards Act. The fire duration calculation program constituting the calculation unit 24A is provided with a function equivalent to the above conditional equation (notification equation) in advance.

Similarly, in the calculation step (S05B) of FIG. 3 , the calculation unit 24B of the second processing unit 30B inputs the data (primary and secondary data) extracted by the extraction unit 22B and the preprocessing unit 23B into the conditional equation defined in Article 3 of Ministry of Construction Notification No. 1433 for each component of the structure to calculate the "indoor fire holding fire resistance time t _fγ ." For example, in the case of a steel frame column, the calculation unit 24B calculates the "fire temperature rise coefficient α,""near-component fire temperature rise coefficient α _l ,""component temperature rise coefficient h," and "critical component temperature T _cγ " based on the data (primary and secondary data) extracted by the extraction unit 22B and the preprocessing unit 23B, and calculates the "indoor fire holding fire resistance time t _fγ " based on the calculated α, α _l , h, and T _cγ . The calculation unit 24B also inputs data (secondary data) indicating the "component heating perimeter H _{s ,} " shown in FIG. 5B, into the conditional equation for calculating the "component temperature rise coefficient h." In addition, the fire-resistance time calculation program constituting the calculation unit 24B is provided with a function corresponding to the above-mentioned conditional formula (notification formula) in advance.

・Decision step (calculation step)
As shown in Fig. 3, calculation steps (S05A, S05B) are followed by determination steps (S06A, S06B, S07). The determination steps (S06A, S06B, S07) correspond to part of the calculation step (S5) in Fig. 1. In this embodiment, the determination step involves two stages of processing: a primary determination step (S06A, S06B) and a secondary determination step (S07). However, the determination step may consist of a single stage of processing, or may consist of multiple stages of processing, including three or more stages.

In the primary determination step (S06A), the determination unit 25A (see FIG. 2) of the first processing unit 30A determines whether the indoor fire duration _tf calculated by the calculation unit 24A is within a predetermined reference range. The determination unit 25A determines "OK (normal)" if the indoor fire duration _tf is within the predetermined reference range, and determines "NG (abnormal)" if the indoor fire duration _tf is outside the reference range. After the primary determination step (S06A), the determination unit 25A passes the indoor fire duration _tf calculated by the calculation unit 24A to the second processing unit 30B (here, the determination unit 25B). The determination unit 25A is realized by a processor reading and executing a calculation program contained in the calculation processing program.

In the primary determination step (S06B), the determination unit 25B (see FIG. 2) of the second processing unit 30B determines whether the indoor fire retention fire resistance time _tfγ calculated by the calculation unit 24B is within a predetermined standard range. If the indoor fire retention fire resistance time _tfγ calculated by the calculation unit 24B is within the predetermined standard range, the determination unit 25B determines it as "OK (normal)," and if the indoor fire retention fire resistance time _tfγ is outside the standard range, the determination unit 25B determines it as "NG (abnormal)."
In the secondary determination step (S07) following the primary determination step (S06B), the determination unit 25B determines whether the indoor fire resistance time is equal to or greater than the indoor fire duration based on the indoor fire resistance time _tfγ calculated by the calculation unit 24B and the indoor fire duration time _tf acquired from the determination unit 25A. The determination unit 25B compares the indoor fire duration calculated by the calculation unit 24A with the indoor fire resistance time calculated by the calculation unit 24B to determine whether the indoor fire resistance time is equal to or greater than the indoor fire duration for each component (major structural component such as a wall, column, beam, etc.). The determination unit 25B is realized by the processor reading and executing a calculation program included in the calculation processing program.

The determination unit 25 may perform other determinations. For example, when the processing unit calculates the outdoor fire-resistance time, the determination unit 25 may determine, for each component (a main structural component such as a wall, a pillar, or a beam), whether the outdoor fire-resistance time is equal to or greater than a predetermined time (one hour or more for a portion at risk of fire spreading, and 30 hours or more for other portions).
If the determination unit 25 determines that the result is "NG (abnormal)," the primary data and secondary data may be reset, and the BIM model 14 may be reset (resetting step). This resetting step will be described later.

Output Step As shown in Fig. 3, after the determination steps (S06A, S06B, S07), an output step (S08) is performed. The output step (S08) corresponds to the output step (S7) in Fig. 1. In the output step (S08), for example, the calculation results are displayed on a display, printed, or saved. An example of output in the output step will be described below.

The check table creation unit 26 (see FIG. 2) creates a check table and outputs the created check table. The check table creation unit 26 is realized by the processor reading and executing the performance verification program.
First, the check list creation unit 26 acquires data (result data) of the processing results by the calculation processing unit 30 (30A, 30B) from the calculation processing unit 30. The result data acquired by the check list creation unit 26 includes, for example, the primary data extracted by the extraction unit 22 (extraction units 22A, 22B), the secondary data calculated by the preprocessing unit 23, data such as the fire duration and fire-resistance time calculated by the calculation unit 24, and data of the determination result by the determination unit 25. Note that the check list creation unit 26 acquires the result data of the calculation processing unit 30 (30A, 30B) in association with each room (in association with the room ID number) or each component (in association with the component ID number).
Next, the checklist creation unit 26 creates a checklist based on the result data acquired from the calculation processing unit 30 (30A, 30B) and displays the created checklist on the display. For example, the checklist creation unit 26 displays a list on the display as a checklist, which associates the rooms set in the room setting step (see S02 in FIG. 3 ), the indoor fire durations corresponding to the rooms, and the various data (primary data, secondary data, etc.) used to calculate the indoor fire durations. This makes it easy to confirm the indoor fire durations and the data used to calculate the indoor fire durations. Also, for example, the checklist creation unit 26 displays a list on the display as a checklist, which associates the components of a structure with the indoor fire fire resistance times corresponding to the components and the various data (primary data, secondary data, etc.) used to calculate the indoor fire fire resistance times. This makes it easy to confirm the indoor fire fire resistance times and the data used to calculate the indoor fire fire resistance times.
The checklist creation unit 26 may include the judgment results of the judgment unit 25 (25A, 25B) in the checklist. This makes it easier to identify the room or component that has become abnormal when the judgment result is NG (abnormal). It also makes it easier to check the various data (primary data, secondary data, etc.) that are the basis for calculating the indoor fire duration and indoor fire resistance time that became abnormal, making it easier to confirm the cause of the abnormality.

In the above explanation, the checklist creation unit 26 displays a checklist on the display, but instead of a checklist, the checklist creation unit 26 may display a table included in a calculation sheet (described below) as a checklist. Furthermore, instead of displaying a checklist on the display, the checklist creation unit 26 may print the checklist or save the checklist in a data storage unit (not shown).

In the output step (S08), a calculation sheet may be output. For example, as shown in FIG. 2, the determination unit 25A of the first processing unit 30A creates and outputs a fire duration calculation sheet. Furthermore, the determination unit 25B of the second processing unit 30B creates and outputs a fire retention fire resistance time calculation sheet.

Figure 8 is an explanatory diagram of an indoor fire duration calculation sheet. The determination unit 25A creates the indoor fire duration calculation sheet shown in the figure based on the result data of the first processing unit 30A (primary data extracted by the extraction unit 22A, secondary data calculated by the preprocessing unit 23A, data such as fire duration calculated by the calculation unit 24A, and data on the determination results of the determination unit 25A). The indoor fire duration calculation sheet includes the indoor fire duration corresponding to each room and various data that forms the basis for calculating the indoor fire duration. The determination unit 25A may output the created indoor fire duration calculation sheet to a printer for printing, may display it on a display, or may store it in a data storage unit (not shown).

Figure 9 is an explanatory diagram of an indoor fire fire resistance time calculation sheet. The determination unit 25B creates an indoor fire fire resistance time calculation sheet based on the result data from the second processing unit 30B (primary data extracted by the extraction unit 22B, secondary data calculated by the preprocessing unit 23B, data such as fire fire resistance time calculated by the calculation unit 24B, and data on the determination result from the determination unit 25B) and the result data from the first processing unit 30A obtained from the first processing unit 30A. The indoor fire fire resistance time calculation sheet includes the indoor fire fire resistance time corresponding to each component (indoor fire fire resistance time in the figure), the determination results, and various parameters that serve as the basis for calculating the indoor fire fire resistance time. The determination unit 25B may output the created indoor fire fire resistance time calculation sheet to a printer for printing, display it on a display, or store it in a data storage unit (not shown).

The documents output in the output step (S08) are not limited to calculations such as fire duration calculations and fire resistance time calculations, but may also be, for example, application forms for building confirmation applications. In this embodiment, the performance verification system 20 uses the performance verification program to create various documents (calculation forms, application forms) based on data collected from the BIM model 14. This allows data linkage between the BIM model 14, which represents a three-dimensional model of the structure, and the various documents, thereby reducing the work required to confirm consistency between the two. Furthermore, since consistency between the BIM model 14 and the various documents is assured, a reduction in review time can also be expected.

In the output step (S08), a drawing of the structure created based on the BIM model may be output in which information related to the calculation results of the calculation unit 24 (24A, 24B) is superimposed. This point will be described below.
As shown in FIG. 2 , the determination unit 25 (25A, 25B) stores the data (result data) resulting from the processing by the calculation processing unit 30 (30A, 30B) in the 3D model system 10 as the extended data 16 of the BIM model 14. The display unit 27 (27A, 27B) then creates a drawing of the structure based on the BIM model 14 of the 3D model system 10, and also creates a drawing in which information related to the calculation results, such as fire duration and fire resistance time, contained in the extended data 16, is superimposed on the drawing of the structure. By creating a drawing in which information related to the calculation results of the calculation unit 24 is superimposed on the drawing of the structure created based on the BIM model 14, it becomes easier to confirm the consistency between the drawing of the 3D model of the structure and the calculation results. Although the display unit 27 (27A, 27B) is depicted separately from the commissioning system 20 in FIG. 2 , it is actually configured by the performance verification program of the commissioning system 20 and is included in the commissioning system 20.

Figure 10 is a plan view showing the fire duration. The display unit 27A creates a plan view of the structure based on the BIM model 14 of the 3D model system 10, and also creates a drawing in which each room is color-coded according to the fire duration data included in the extended data 16A. Note that each room shown in the plan view is based on the setting data set in the room setting step (S02) of Figure 3. In this way, the display unit 27A shows each room on the plan view based on the BIM model 14 of the 3D model system 10, and also creates a drawing in which information related to the fire duration calculated by the calculation unit 24A is associated with each room and superimposed on the plan view. Note that instead of color-coding each room according to the fire duration, the display unit 27A may also create a drawing in which a numerical value indicating the fire duration is written for each room. The display unit 27A may also create a framing plan showing the fire duration. As shown in Figure 10, by overlaying information about the fire duration (calculation results) on a floor plan of a structure based on the BIM model 14, it becomes easier to check the consistency between the BIM model 14 and the calculation results.

If the determination unit 25 (25A, 25B) determines an abnormality in the fire duration or fire resistance time, it is desirable for the display unit 27A to create a drawing that identifies the room related to the fire duration and a drawing that identifies the components related to the fire resistance time. This makes it easy to check whether the determination result is abnormal, and to identify the rooms or components that will result in an abnormal determination. A specific example of this is described below.

Figure 11 is an explanatory diagram of a 3D display showing components whose indoor fire resistance time is shorter than the indoor fire duration. The display unit 27B creates a drawing of the structure based on the BIM model 14 of the 3D model system 10. If there are components whose indoor fire resistance time is shorter than the indoor fire duration (components whose indoor fire resistance time is shorter than the indoor fire duration), the display unit 27B creates a drawing that identifies the components whose indoor fire resistance time is shorter than the indoor fire duration, for example, by highlighting the components. While Figure 11 shows a drawing in which the structure and components are displayed in 3D, the display unit 27B may also display the structure and components in plan or elevation views. This makes it easier for workers to confirm the presence or absence of components whose indoor fire resistance time is shorter than the indoor fire duration (components whose indoor fire resistance time is shorter than the indoor fire duration) and to locate components whose indoor fire resistance time is shorter than the indoor fire duration. As shown in Figure 11, overlaying information related to the calculation results of the indoor fire resistance time on a drawing of the structure based on the BIM model 14 facilitates the task of verifying consistency between the BIM model 14 and the calculation results.

The display unit 27 (27A, 27B) stores the created drawing data in the extension data 16 of the 3D model system 10 as output data. However, the display unit 27 (27A, 27B) may also store the created drawing data in a data storage unit (not shown) of the commissioning system 20. The commissioning system 20 may output drawings based on the output data of the extension data 16 of the 3D model system 10. For example, as shown in FIG. 2, the commissioning system 20 may output drawings based on the output data of the extension data 16 (e.g., the drawing data shown in FIGS. 10 and 11) as part of the application form. This reduces the work required to confirm consistency between the BIM model 14, which represents a 3D model of the structure, and the application form, since data is linked between the BIM model 14 and various documents. Furthermore, the reliable consistency between the BIM model 14 and various documents is expected to shorten the application review time.
The display unit 27 (27A, 27B) may store the created drawing data in the extended data 16 of the three-dimensional model system 10 as confirmation data for the worker (designer) to check.

As described above, when the determination unit 25 determines that the result is "NG (abnormal)," the primary data and secondary data may be reset, and the BIM model 14 may be reset (resetting step). This resetting step will be described below.

If the determination unit 25A determines that the indoor fire duration is abnormal in the primary determination step (S06A), the determination unit 25A changes the room data related to the indoor fire duration (e.g., primary data and secondary data such as floor area and types of interior building materials; data to be input into the conditional equation of the calculation unit 24A). Note that the resetting program included in the calculation processing program has resetting patterns prepared in advance, and the determination unit 25A changes the data of the predetermined parameters in accordance with the resetting pattern corresponding to the fire duration calculated by the calculation unit 24A.
Furthermore, in the primary determination step (S06B), if the determination unit 25B determines that the indoor fire retention time is abnormal, the determination unit 25B changes the data of the components related to the indoor fire retention time (for example, primary data and secondary data such as the type of component and various dimensions of the component; data to be input into the conditional equation of the calculation unit 24B). Note that the determination unit 25B changes the data of the predetermined parameters according to a reset pattern prepared in advance in the reset program.
Furthermore, if the determination unit 25B determines in the secondary determination step (S07) that the indoor fire resistance time is shorter than the indoor fire duration, the determination unit 25B changes the room data related to the indoor fire duration and the component data related to the indoor fire resistance time. The determination unit 25B changes the data of the predetermined parameters according to a reset pattern prepared in advance in the reset program.
The resetting of the primary data and secondary data does not have to be performed automatically using a resetting program. For example, a setting screen may be displayed on a display, and an operator may input data for predetermined parameters using an input device (keyboard, mouse, etc.), and the data may be set according to the operator's input. In this case, it is desirable that only data related to rooms or components determined to be abnormal can be input on the setting screen displayed on the display. This can reduce input errors by the operator.

After the determination unit 25 (25A, 25B) changes the specified data (primary data and secondary data), the calculation unit 24 (24A, 24B) inputs the changed data into the condition equation (notification equation) and performs a recalculation. That is, the calculation unit 24 (24A, 24B) performs the calculation steps (S05A, S05B) again based on the reset data. The determination unit 25 (25A, 25B) then performs the determination steps (S06A, S06B, S07) again based on the calculation results (indoor fire duration, indoor fire retained fire resistance time) calculated in the new calculation steps (S06A, S06B). In this way, the calculation processing unit 30 (30A, 30B) repeatedly resets data based on the calculation results in the calculation steps and performs recalculation based on the reset data. This derives data that is compliant with the Fire Resistance Performance Verification Method.

After the data has been reset, if the judgment unit 25 judges it to be "OK (normal)," as shown in FIG. 2, the judgment unit 25 saves the reset data in the extended data 16 (16A, 16B) of the 3D model system 10. The reset data is saved in the extended data 16 as data with common parameters with the data (primary data) extracted by the extraction unit 22. The worker (designer) configuring the BIM model can compare and consider the reset data saved in the extended data 16 with the original data of the BIM model 14 that has the same parameters as the reset data, and decide whether to change the original data of the BIM model 14 to the reset data. Instead of the worker deciding whether to change to the reset data, the reset program may automatically change the original data of the BIM model 14 to the reset data. Because the reset data reflects the calculation results (indoor fire duration, indoor fire resistance time) of calculation steps (S05A, S05B), changing the original data of BIM model 14 to the reset data resets BIM model 14 based on the calculation results (indoor fire duration, indoor fire resistance time) of calculation steps (S05A, S05B). Resetting the BIM model based on the calculation results (indoor fire duration, indoor fire resistance time) of calculation steps (S05A, S05B) in this way makes it easier to set structures that comply with the Fire Resistance Verification Act in BIM model 14. Furthermore, because data linkage is established between the 3D shape information (shape data) and attribute information (attribute data) that make up the structure's 3D model and the calculation procedures for the verification method specified in the notice, the work required to confirm consistency between the two is reduced.

<Summary>
As described above, the commissioning method of this embodiment includes a 3D model setting step (see S1 in FIG. 1 and S01 in FIG. 3 ) in which a BIM model 14 (an example of a 3D model) of a structure having a space composed of components is set in the 3D model system 10; an extraction step (see S3 in FIG. 1 and S03 in FIG. 3 ) in which the commissioning system 20 extracts data indicating conditions related to the space or components from the BIM model 14; and a calculation step (see S5 in FIG. 1 and S05A and S05B in FIG. 3 ) in which the commissioning system 20 inputs the extracted data into a pre-prepared conditional equation using a calculation program for verifying the performance of the structure. This commissioning method simplifies the process of verifying the consistency between the 3D model data of the structure and the calculations based on the commissioning method, thereby reducing the workload of verifying the consistency between the two. Furthermore, this commissioning method eliminates input errors when entering data for fire resistance performance verification, improving the efficiency and reliability of input information verification.

In addition, in the above-described embodiment, the BIM model 14 (an example of a three-dimensional model) is reset based on the calculation results from the calculation steps. Specifically, the performance verification system 20 (an example of a computer) performs a primary judgment (S06A, S06B) and a secondary judgment (S07) based on the calculation results (indoor fire duration, indoor fire resistance time) from the calculation steps S04A and S04B. If the judgment result is abnormal, the room data related to the indoor fire duration and the component data related to the indoor fire resistance time are changed (reset) based on the calculation results. Furthermore, the original data on the BIM model 14 with parameters common to the reset data is changed (reset) to the reset data, thereby resetting the BIM model 14. This facilitates the design of structures that meet the requirements for fire resistance verification.

The aforementioned calculation program calculates the fire duration of a structure (see S05A in FIG. 3). In this way, by using the calculation program to calculate the fire duration of a structure based on parameters extracted from the BIM model 14 (an example of a three-dimensional model), it is possible to reduce the work of checking the consistency between the three-dimensional model data of the structure and the calculation of the fire duration.
The aforementioned calculation program also calculates the fire-resistance time of the structure (see S05B in FIG. 3). By using the calculation program to calculate the fire-resistance time of the structure based on parameters extracted from the BIM model 14 (an example of a three-dimensional model), the work of verifying consistency between the three-dimensional model data of the structure and the calculated fire-resistance time can be reduced. The fire-resistance time calculated by the calculation program is not limited to the indoor fire-resistance time, but may also be the outdoor fire-resistance time.

The calculation program may also verify performance other than fire resistance performance verification. For example, the performance verification system 20 may perform evacuation safety verification or verification related to normal fires and fire spread prevention based on data extracted from the structure's BIM model 14 (an example of a three-dimensional model). For example, when performing evacuation safety verification, the performance verification system 20 may extract data indicating spatial or component conditions from the structure's BIM model 14 (an example of a three-dimensional model) (extraction step), and then use a calculation program for evacuation safety verification to input the extracted data into a pre-prepared conditional formula (a conditional formula defined for evacuation safety verification) to calculate various times, walking distances, etc.

The aforementioned calculation program also includes a fire duration calculation program that calculates the fire duration of a structure, and a fire retention fire resistance calculation program that calculates the fire retention fire resistance of a structure. This reduces the work required to check the consistency between the structure's 3D model data and the calculations of the fire duration and fire retention fire resistance.

The performance verification system 20 also performs a determination step (S06A, S06B, S07) to determine whether at least one of the fire duration and fire retention time is normal (abnormal). The performance verification system 20 also determines whether the indoor fire retention time is equal to or greater than the indoor fire duration (see S06 in Figure 3; secondary determination step). In this manner, in this embodiment, an extraction program extracts data from the BIM model 14 (an example of a 3D model), a calculation program calculates the fire duration and fire retention time, and a determination of normality (abnormality) is made based on the calculation results, thereby reducing the work required to confirm consistency between the structure's 3D model data and the determination results.

Furthermore, if the performance verification system 20 determines in the determination steps (S06A, S07) that there is an abnormality in the fire duration, it identifies the room related to the fire duration. Note that, as a method of identifying the room, for example, when outputting a plan view showing the fire duration (see FIG. 10), the room is color-coded according to the calculation result of the indoor fire retained fire resistance time, and the color of the room with the determination result of NG (abnormal) is changed to a warning color (for example, red) or the room name or identification number is highlighted, but other methods are also possible.
Furthermore, if the performance verification system 20 determines in the determination steps (S06B, S07) that there is an abnormality in the fire retention fire resistance time, it identifies the components related to the fire retention fire resistance time. Note that the method for identifying the components is not limited to the method of highlighting the components on a 3D display of the structure as shown in, for example, FIG. 11 , and other methods may be used. For example, components with a judgment result of NG (abnormal) may be highlighted on a floor plan (see FIG. 10) or a framing plan, or the column for components with a judgment result of NG (abnormal) may be highlighted in the indoor fire retention fire resistance time calculation sheet (see FIG. 9).
As described above, by having the performance verification system 20 identify the rooms and components, it becomes easy to check whether or not the judgment result is abnormal, and to check the rooms and components that will result in an abnormal judgment result.

The performance verification system 20 also uses a fire duration calculation program to create a fire duration calculation sheet (see Figures 2 and 8), and uses a fire fire resistance time calculation program to create a fire fire resistance time calculation sheet (see Figures 2 and 9). As shown in Figure 8, the indoor fire duration calculation sheet includes the indoor fire duration and various data used to calculate the indoor fire duration. As shown in Figure 9, the indoor fire fire resistance time calculation sheet includes the indoor fire fire resistance time and various data used to calculate the indoor fire fire resistance time. The various data shown in these calculation sheets are based on data extracted from the 3D model data. In this way, data linkage is established between the 3D model data of the structure and the calculation sheets, reducing the work required to confirm consistency between the two.

The performance verification system 20 also outputs drawings created based on the BIM model 14, with information about the calculation results from the calculation step (e.g., fire duration and fire resistance time) superimposed on the drawings (see Figures 10 and 11). This makes it easier to check the consistency between the BIM model 14 and the calculation results.

Furthermore, after extracting primary data from the BIM model 14 in the extraction step, the performance verification system 20 performs a preprocessing step to convert the primary data into secondary data that can be input into a conditional equation (see S04 in Figure 3). As a result, even if the BIM model 14 does not contain data synonymous with parameters that can be input into a conditional equation, the preprocessing step can interpolate the data to be input into the conditional equation.

6, a conversion table 43 that associates primary data with secondary data is prepared in advance, and the performance verification system 20 converts the primary data extracted from the BIM model 14 into secondary data in the preprocessing step described above (see S04 in FIG. 3) based on the conversion table 43. By using the conversion table in this way, it is possible to interpolate the secondary data to be input into the conditional formula.
In addition, in the pre-processing step (see S04 in FIG. 3), secondary data is calculated by inputting primary data into a conversion formula prepared in advance. For example, in the extraction step, primary data indicating the steel height H, steel width B, web thickness _t1 , and flange thickness _t2 are extracted from the BIM model 14, and the values of these primary data are input into the conversion formula shown in FIG. 7 to calculate data (secondary data) indicating the parameter "heated perimeter _Hs of the member." By inputting primary data into the conversion formula in this way, it is possible to interpolate the secondary data to be input into the condition formula.
