摘要

摘要: 采用足尺模型试验方法对预压装配式预应力混凝土梁柱组合件在低周反复荷载作用下的开裂破坏形态、滞回特性、骨架曲线、刚度退化特征、耗能能力、梁端转动变形等抗震性能指标进行了系统研究。试验及理论分析结果表明，预压装配式预应力混凝土梁柱组合件具有较强的耗能能力，能够满足抗震设防的要求。由于预应力筋的作用，卸载后残余变形较小，恢复性能较好。梁柱结合部位是该节点的关键部位，经过合理的设计，采取必要的措施，还可改进其耗能能力。

Abstract: By using full-scale model test method,the seismic behavior indexes of prestressed precast concrete beamcolumn assemblies under low-cyclic reversed load are studied,such as failure pattern,hysteretic characteristic,skeleton curve,stiffness deterioration,energy dissipation and rotation of the beam end. The results indicate that this kind of assembly has better energy dissipation and enough displacement restoring capacity by prestressed tendons. It is also suggested that some measures should be taken to improve its seismic behavior.
