Description

  The present invention relates to a technique for evaluating a design in a building design process.

  2. Description of the Related Art Conventionally, design data (design drawings) for buildings such as houses has been created using a CAD (Computer Aided Design) system. Based on the design data created by this CAD system, a structure calculation using structure calculation software is performed by a computer (electronic computer), and the design is evaluated. In recent years, the design, manufacture, and process design of products that have been simulated by computer technology have been performed using a CAE (Computer Aided Engineering) system.

  The deformation amount of the structural member of the building calculated by the structural calculation is used for evaluating the performance of the floor or the like. In general, the evaluation value for evaluating the deformation of the structural member is a ratio between the length of the unit structural member and the amount of deformation. For example, the deformation evaluation value for a beam is a ratio of the deformation amount to the span of the beam. For example, in the case of a floor of a house, up to 1/300 of the beam span is set as the allowable value of the deformation evaluation value. If the deformation evaluation value exceeds the allowable value, the cross-sectional area of the beam is increased, or the span of the structural member including the beam is decreased to take measures for reducing the deformation amount. .

However, when the deformation of the floor is evaluated by the structure evaluation method as described above, the evaluation is based on the deformation amount of the beam, and the deformation amount as the floor surface is not evaluated. When the structure of a building floor is evaluated based on the amount of deformation of the beam, there are cases where the validity of the evaluation is questionable. For example, if there are two adjacent beams and one beam is hardly deformed, the other beam is greatly deformed within the allowable value, so that the floor between these beams exceeds the allowable range. This is the case that will occur.

The display unit 67 is a display, and displays, for example, calculation results such as design data, first structure calculation result data, second structure calculation result data, pass / fail determination result data, and a three-dimensional structure diagram of a building frame. It is for output.

  Next, the process flow of the design evaluation apparatus 10 will be described with reference to the flowchart shown in FIG.

First, the structure calculation unit 11 of the design evaluation device 10 acquires design data from the CAD device 15 and stores it in a database, reads this design data (S01), and creates beam deformation analysis data (S02). The design data may be obtained directly from the CAD device 15 without being stored in the database of the design evaluation device 10, or may be obtained from data stored in a portable storage medium.
