Abstract:ANSYS was used to study the influence of joint stiffness on the seismic performance of the self-standing angle steel tower. An angle steel tower model considering the joint stiffness was established, and the elasto plastic time-history analysis was carried out on the angle steel tower under the three dimensional rare earthquake, and the influence of the joint stiffness on the internal force and displacement of the structure under the earthquake action was studied. The analysis results show that the joint stiffness has a significant impact on the seismic performance of the structure.

Keywords:self-standing angle steel tower; joint stiffness; elasto plastic time-history analysis; seismic response
