摘要
利用有限元分析软件ANSYS对某正放四角锥网架进行结构静力分析、模态分析和时程分析,得到该网架的模态频率和振型,在此基础上对比分析了网架在不同地震波作用下的最大位移,并得出一些有益的结论。
This article makes structural static analysis,modal analysis,and time-history analysis for the orthogonal quadrangular spatial grid structure by using finite element software ANSYS,and concludes its modal frequency and mode of vibration.And then,it compares and analyzes the maximum displacement of the grid under different earthquake,and draws some beneficial conclusions.
