Analysis of nonlinear deformation relationship between steel-plastic grid and membrane structure based on Abaqus software

Abstract

In this paper, Abaqus finite element software is used to calculate the nonlinear deformation value of steel-plastic grid and building membrane structure under the action of uniform load, which lays the foundation for similar engineering applications and software calculation in the future. The specific conclusions are as follows: 1) With the continuous increase of the uniform load, the displacement change of the steel-plastic grid is always greater than the displacement change of the building membrane structure, and the nonlinear change curve trends of the two are consistent. 2) Both showed that the deformation value of the center point range showed a nonlinear growth trend with the increase of the load. 3) With the continuous increase of the applied uniformly distributed load, the rate of deformation increase is also significantly increased.
