摘要

摘要: 自复位结构具备良好的耗能和自复位性能,能控制结构地震响应,减小结构残余层间位移角,降低结构损伤。对新型装配式干连接自复位节点性能进行研究,介绍有限元建模过程,同时设置现浇节点进行对比研究。通过有限元模拟,研究节点强度、刚度、应力分布及破坏机理、抗震性能和节点性能影响参数。研究表明:干连接自复位节点初始刚度与现浇节点相当,具有较强的耗能能力和自复位性能,同时节点性能主要受预应力筋初始预拉力和耗能螺栓屈服强度影响。

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.
