Abstract

Abstract

In order to solve the problem that traditional prefabricated steel frame structures have large residual deformation and cannot be effectively self-centering, a new steel frame structure with self-centering column base joints was proposed. The static analysis of 8 frame models was carried out by the finite element software ABAQUS. The influence of the thickness of the cover plate weakened by dog bone, the initial cable force and the axial compression ratio on the bearing performance of the new frame were systematically studied. The results showed that the bearing capacity of the new self-centering frame was less than 5% and the residual deformation was reduced by more than 50% compared with the traditional steel frame with rigid column base joints. The bearing capacity of the new steel frame was mainly affected by the thickness of the cover plate weakened by dog bone, the initial cable force, and the axial force at the top of the column. The frame could achieve the same bearing capacity and self-centering effect under different parameter combinations.
