Abstract

Abstract

The self-centering structure has good energy dissipation and self-centering performance, which can control the seismic response of the structure, reduce the displacement angle between the residual layers of the structure, and reduce the damage of the structure. This paper studies the performance of the new prefabricated dry connection self-centering joints, and specifically introduces the modeling process using the finite element software ABAQUS. At the same time, the cast-in-place joints are set for comparative research. The failure mechanism, seismic performance and the parameters affecting the joint performance are analyzed by finite element analysis. The research shows that the initial stiffness of the dry connection self-centering joint is equivalent to that of the cast-in-place joint, and it has strong energy dissipation capacity and self-centering performance; in the meanwhile, the joint performance is mainly affected by the initial pretension of prestressed reinforcement and the yield strength of dissipated bolt.
