A method for transforming a building structure model

Abstract

The invention relates to a method for converting a building structure model, which is used for mutual conversion of building structure models between different finite element softwares, comprising steps: S1: converting the source finite element model in the source finite element software into a CAD model; S2: converting the source finite element model into a CAD model; The CAD model is transformed into the target finite element model in the target finite element software. Compared with the prior art, the invention makes the CAD file a transfer station for transformation of various finite element software. Since the data formats of the current finite element analysis software vary greatly, while the CAD file format is relatively standard and uniform, the number of pairs of conversions between finite element software is huge, and it is difficult to develop software interfaces. Greatly reduce the required conversion combinations and reduce the difficulty of development.

Description

technical field [0001] The invention relates to the technical field of building structures, in particular to a method for transforming building structure models. Background technique [0002] The finite element method is the most important technique in the field of structural analysis today. After decades of development, the finite element method has been quite mature, and many reliable engineering-oriented commercial software have appeared, including general finite element software (such as ANSYS, ABAQUS), and special finite element software in the field of civil engineering (such as SAP2000, Midas). etc. The finite element model stores the attributes of the component elements except the geometric information. At present, there is no uniform file format standard, and the file formats of various finite element analysis software on the market are different. Simple modeling methods are usually integrated in finite element software, which can meet the modeling requirements of ...

Problems solved by technology

[0003] However, similar to the evolution of cars from straight lines to more aerodynamic and graceful streamlines, with the development of computer-aided design technology, the shapes of many contemporary buildings have become more complex and diverse due to the needs of form or function

These structures with complex spatial shapes cannot be described by the traditional architectural axis method, so the traditional method of directly establishing a wireframe model in finite element software for analysis based on architectural drawings and axes is becoming more and more difficult, and in many cases it is even completely unfeasible

[0004] Since the format of finite element analysis software is not uniform, it is difficult to convert in various finite element software. Although there are some conversion tools on the market, such as figure 2 As shown, but due to the large number of finite element software and different versions, many converters are needed, and the conversion results are uneven.

Building Information Modeling (BIM) technology is a possible solution in the future, but because the corresponding computer software and hardware technology is far from mature, and a large number of engineering designers are still very unfamiliar with BIM technology
