Visual structure analysis system

Abstract

The invention relates to a visual structure analysis system, which belongs to the technical field of building structure modeling systems. The visual structure analysis system comprises a front preprocessing module, a computing module and a postprocessing module, and the modeling and analytic processes of building structures comprise the following steps: preprocessing, namely using the basic drawing function of the preprocessing module to establish a structure model, and adding various loads and boundary conditions on the structure model; computation, namely using the computing module to read in an input data file formed by the preprocessing module and performing the computation; and postprocessing, namely according to a postprocessing file formed by the computing module, drawing various corresponding graphs on the structure model. The invention provides a technical scheme for the visual structure analysis system, wherein spatial structure models for various buildings can be conveniently, accurately and quickly established, and the processes for establishing the overall models are completely visual. The visual structure analysis system achieves the automation of structural modeling, greatly improves the modeling speed, and simultaneously greatly improves the visualization degree of models.

Description

technical field [0001] The invention belongs to the technical field of building structure modeling systems, and in particular relates to a visual structure analysis software that can observe the modeling process in real time. Background technique [0002] After more than 30 years of development, structural analysis has become relatively mature, and now there are many general and special structural analysis software at home and abroad. Earlier, the input data files required by the calculation program were written by the user and then input into the computer. For more complex structures, this process is extremely cumbersome and error-prone. Modern building structures are becoming more and more complex, and the scale is also increasing. There are often thousands of rods in general building structures, and it is unrealistic to manually write input data files. At present, all structural analysis programs have a pre-processing part, but the pre-processing function of many program...

Earlier, the input data files required by the calculation program were written by the user and then input into the computer. For more complex structures, this process is extremely cumbersome and error-prone

Modern building structures are becoming more and more complex and larger in scale. General building structures often have thousands of rods, and it is unrealistic to manually write input data files.

At present, all structural analysis programs have a pre-processing part, but many programs have weak pre-processing functions, mainly because the modeling process is cumbersome, the degree of automation is not high, and it is inconvenient to modify

For example, the well-known finite element analysis software ANSYS, the modeling process of the complex space grid is very troublesome. It needs to find out the functional relationship of the grid member layout, and then use the *DO loop command flow to realize the modeling process. For For many complex structures, the functional relationship is not easy to find out, and some structures cannot find the functional relationship at all

[0003] In addition, since ANSYS is one of the most famous finite element analysis software in the world, many CAD software have interfaces with it, and can convert the modeling results of other CAD software into ANSYS data, but most of these CAD software The modeling results of the model are converted to ANSYS data, and there is a lack of software to convert building structures into ANSYS data
