摘要
本文以工程实例为背景,通过使用大型有限元分析程序ANSYS10.0,建立模型,并根据规范要求,采用模态分析和振型分解反应谱法分析,对某商场框架结构进行了动力特性分析,得到了该结构桁架部分的自振频率、弯矩、剪力、轴力、结构位移分布等参数,得出一些有益的结论,为该结构的设计提供了依据,并为同类研究提供参考。
Based on a frame structure design projects,and,using the large-scale finite element analysis program ANSYS10.0,setting up models and analyzing with response spectrum and modal methods,this study focuses on the analysis of the dynamic performance of the frame structure in a Fuzhou shopping center.Through the analysis,we obtained parameters of the structure base frequency,the bending moment,shear,axial force and the structure displacement distribution of the truss structure.It is expected that the result of our analysis can provide some useful suggestions for the structure design and reference for similar studies.
