以某网架屋盖结构为工程背景,利用大型有限元软件ANSYS对网架结构进行了静载作用下受力和变形分析。并通过对网架结构模态的分析,发现网架的振型以前28阶振型为主。
Taking a grid roof structure as the engineering background, the finite element software ANSYS was used to analyze the stress and deformation of the grid structure under static load. And through the analysis of the modal structure of the grid, it is found that the first 28 modes of the former are the mode shapes of the grid.
