FINITE ELEMENT ANALYSIS OF PORTAL RIGID FRAME BASED ON ANSYS
A finite element analysis was conducted on a portal frame structure using ANSYS,a large-scale general finite element software.Consider the influence of different connection methods at the upper end of wind re-sistant columns on structural deformation and internal forces of supports.The results indicate that different connec-tion methods at the upper end of the wind resistant column have little effect on the deformation of the structure and the internal forces of the supports;At the same time,response spectrum analysis was conducted on the structure,and a conclusion with reference significance was finally obtained.
