| Abstract: | 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 o... |
