Problems solved by technology

However, the current design and construction mainly rely on experience and lack systematic and scientific theoretical basis
Especially for construction technicians, there is no mature virtual technology that allows them to intuitively predict the location of dangerous points in buildings, so as to make scientific preparations

Embodiment Construction

[0020] The hardware environment that the present invention is used for implementing is pentium-4 4.2G computer, 2G memory, 512 graphics cards, and the environment of operation is ansys11.0, 3DMAX10.0, VC++6.0 and WindowsXP

[0021] The method proposed by the present invention is realized by using the combination of VC++ programming language and other programs.

[0022] The basic idea of ​​the present invention is: use ANSYS to establish the migration wireframe model of a six-story frame structure building, analyze the force status of the building under each working condition, and store the analysis results in text format; then use 3Dmax software to establish the building In order to obtain the same point coordinates as in the ANSYS model, it is necessary to divide the triangular mesh of the solid model in 3Dmax according to the number of grids divided in ANSYS; meanwhile, for a more realistic simulation scene, the present invention also establishes a top For the models of lite...

Abstract

The invention discloses a visual modeling method for simulating stress change of a building in a moving process, which comprises the following steps of: establishing a model for simulating the building moving by using ANSYS software, adding restriction and application conditions with different substeps according to the rail unevenness for carrying out transient kinetic analysis on the model, storing node displacements of substep analysis results; and establishing a three-dimensional solid model of the building moving by using 3DMAX (three-dimensional animation), endowing the material attributes, storing as an ASE (Active Seeker Electronics) format. Compared with the prior art, the invention can more accurately predict the position of a danger point of the building, greatly reduce the read data volume, lighten the load of a CPU, highlighting key parts, and solve the problem of incontinuous read numbers by adopting a successive reading method and a segmented displaying method through defining a structure body and a map structure. Meanwhile, the successive reading method and the segmented displaying method are used for displaying stress change of the building, i.e. read displacement variable and color depth.

Description

technical field [0001] The invention relates to a computer simulation technology for building migration, in particular to a visual modeling method for modeling and simulating stress changes in the process of non-solid model building migration by using ANSYS. Background technique [0002] With the rapid development of economic construction, in the process of urban planning, old city reconstruction, road widening and demolition of buildings, buildings that have been put into use for a short time and are in good condition, or have special functions that are not suitable for demolition are often encountered. In such a situation, the traditional approach is to dismantle and then dispose of the abandoned construction waste at a high cost, and choose a new site for reconstruction. This not only causes huge waste and economic losses, but also affects some ancient buildings with historical value. It is a very regrettable and helpless move that the reservation cannot be restored. The...
