Such a deck plate has directionality as its strength characteristic. That is, in the structural calculation of the structure using the deck plate, it is necessary to input the direction of the deck plate as necessary information for the strength calculation.

Can be done. Further, once the orientation of the deck plate is determined, it is possible to omit inputting calculation conditions such as the floor load transmission direction.

Further, if the orientation of the deck plate is determined in consideration of the presence or absence of the beam, the orientation of the deck plate can be set more appropriately.

In addition, when calculating the strength characteristics of the beam, by adding the strength of the deck plate and the strength characteristics of the concrete placed on the deck plate, more accurate strength characteristics can be calculated, and appropriate structural calculation. It can be performed.

Hereinafter, the structural calculation support system according to the embodiment of the present invention will be described. FIG. 1 is a perspective view showing the deck plate 1. The deck plate 1 is composed of a plate 3, a main reinforcing bar 5, a sub-reinforcing bar 7, and the like.

The plate 3 is, for example, a steel plate having a fine corrugated shape. The main reinforcing bar 5 is arranged and fixed along the longitudinal direction of the plate 3. Further, the auxiliary reinforcing bar 7 is fixed at a predetermined angle with respect to the main reinforcing bar 5. The deck plate 1 configured in this way has a strength against bending in the longitudinal direction (A in the figure) higher than the strength against bending on the short side (B in the figure). That is, the strength characteristics of the deck plate 1 differ depending on the direction thereof.

2A and 2B are plan views showing the arrangement of the deck plate 1, FIG. 2A is a view showing the arrangement of columns 9, girders 11 and girders 13, and FIG. 2B is a view showing the arrangement of deck plates 1. It is a figure which shows the state which was done. As shown in FIG. 2A, a girder 11 is arranged between the four pillars 9. Further, between the girders 11 facing each other, a plurality of girders 13 are fixed substantially parallel to the girders 11.

When the girders 13 are arranged in this way, the distance between the girders 13 (E in the figure) is shorter than the distance between the girders 11 in the direction orthogonal to the girders 13 (D in the figure). In this case, the deck plate 1 is arranged with the direction perpendicular to the beam 13, which is the direction in which the beam spacing is short, as the longitudinal direction of the deck plate 1.

Next, a structural calculation support system that performs the above structural calculation will be described.

The control unit 23 is composed of a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), and the like. The CPU calls and executes a program stored in the storage unit 25, ROM, recording medium, etc. in the work memory area on the RAM, drives and controls each device connected via the bus 37, and controls the structural calculation support system 20.

The ROM is a non-volatile memory, and permanently holds a computer boot program, a program such as a BIOS, data, and the like. The RAM is a volatile memory, and includes a work area used by the control unit 23 to perform various processes while temporarily holding programs, data, and the like loaded from the storage unit 25, ROM, recording medium, and the like.

The storage unit 25 is an HDD (hard disk drive) or SSD (solid state drive), and stores a program executed by the control unit 23, data necessary for program execution, an OS (operating system), and the like. As for the program, a control program corresponding to the OS (operating system) and an application program corresponding to the processing described later are stored. Each of these program codes is read out by the control unit 23 as necessary, transferred to the RAM, read out by the CPU, and executed as various means. Further, various data used in the present invention are stored in the storage unit 25. For example, the strength characteristics of the columns 9, the girders 11 and the girders 13, and the strength characteristics of the deck plate 1 in the longitudinal direction and the lateral direction are stored.

The media input / output unit 27 (drive device) inputs and outputs data, and for example, a floppy (registered trademark) disk drive, a CD drive (-ROM, -R, RW, etc.), a DVD drive (-ROM, -R, etc.) -RW etc.), has a media input / output device such as MO drive.

Here, the structural calculation support system 20 is not limited to the one including all of the above configurations, and may have only the configurations necessary for achieving the functions of the present invention.

Next, the operation of the structural calculation support system 20 will be described. FIG. 5 is a flowchart showing the operation of the structural calculation support system 20. The structural calculation support system 20 calculates the yield strength and deformation of the building at all times and at the time of an earthquake, and it is possible to confirm by calculation whether or not the structure has a desired strength.

First, the input unit 31 inputs calculation conditions including at least the arrangement of columns 9 and beams (girders 11 and girders 13) (step 101). The input conditions may include not only the arrangement of the pillars 9 and the like, but also the model number and size of the members used, or the strength of each member and the like. For example, the type and size of the deck plate 1 and the pillar 9 to be used can be included in the input condition. In this case, the strength characteristic data is stored in advance in the storage unit 25 for each type and size of each member, and is associated with each member.

Next, the control unit 23 determines whether or not there is a beam 13 for each region surrounded by the four pillars 9 (step 102).

When there is a beam 13, the deck plate direction determination unit of the control unit 23 determines the direction perpendicular to the beam 13 as the longitudinal direction of the deck plate 1 (step 103). That is, when there are small beams 13, the distance between the small beams 13 is shorter than the distance between the large beams 11 orthogonal to the distance between the small beams 13, so that the direction in which the distance between the beams is short is defined as the longitudinal direction of the deck plate 1.

On the other hand, when there is no beam 13, the deck plate direction determination unit of the control unit 23 determines that the direction in which the distance between the girders 11 is narrow is the longitudinal direction of the deck plate 1 (step 104). If the distance between the beams is the same, it may be aligned with the direction of the deck plates in other adjacent regions. As described above, the deck plate direction determination unit of the control unit 23 is used for all the regions surrounded by the four columns 9 based on the arrangement of the columns 9 and the beams (girder 11 and beam 13). , The direction in which the beam spacing is short is determined as the longitudinal direction of the deck plate 1.

Next, in step 101, the arrangement of the columns 9 and beams (girders 11 and girders 13) input by the input unit 31, and at least the columns 9, girders 11 and girders 13 read from the storage unit 25. Based on the strength characteristics and the strength characteristics and calculation conditions in each direction of the deck plate 1, the calculation unit of the control unit 23 performs structural calculation of the structural frame and the floor slab (step 105).

In the calculation of the structural frame in the calculation unit of the control unit 23, the strength characteristics of the deck plate 1 and the concrete placed on the deck plate 1 are taken into consideration in addition to the strength characteristics of the beam, and the deck plate 1 is arranged. The strength of the beam is calculated. For example, in the conventional structural calculation, the strength calculation of the beam and the strength characteristic of the floor slab 15 are calculated separately, but in the present embodiment, the floor slab 15 is integrally constructed on the beam by a stud connector or the like. As a structure, the strength of the beam is calculated. By doing so, more accurate strength calculation can be performed. Therefore, it is not necessary to select a beam having excessive strength, and an appropriate beam can be selected.

Next, the control unit 23 outputs the structural calculation result of the structural framework and the floor slab calculated by the calculation unit to the output units such as the display unit 33 and the media input / output unit 27 (step 106). From the above, the structural calculation can be performed.

As described above, according to the present embodiment, the arrangement direction of the deck plate 1 is automatically determined without inputting to the system by the user, so that it is possible to save the trouble of inputting. At this time, by setting the side with the short beam spacing as the longitudinal direction of the deck plate 1, the direction in which the strength of the deck plate 1 is high can be applied to the direction in which the strength of the structure is weak, and the structure can be efficiently applied. Strength characteristics can be improved.

Further, by considering the presence or absence of the beam 13, the direction of the deck plate 1 can be determined more appropriately.

Further, in the calculation of the structural frame, the strength of the beam can be calculated more accurately by adding the strength characteristics of the deck plate 1 and the concrete placed on the deck plate 1 to the strength characteristics of the beam.

Although the embodiments of the present invention have been described above with reference to the attached drawings, the technical scope of the present invention does not depend on the above-described embodiments. It is clear that a person skilled in the art can come up with various modifications or modifications within the scope of the technical ideas described in the claims, and these are naturally within the technical scope of the present invention. It is understood that it belongs to.
