摘要
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。
With a grid structure roof as the engineering background, the anal- ysis of the stress and deformation under static load was given for the grid roof structure by using the finite element software ANSYS, and through the modal analysis of the grid structure, it was found out that the vibration modes of the preceding 28 orders dominate the mode of vibration of the grid structure.
