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。 Full-scale model test is used to analyze the failure modes, hysteresis characteristics, skeleton curves, stiffness degeneration characteristics, energy dissipation capacity and deformation of beam ends under preloading of prestressed concrete beam-column assemblies under low cyclic loading Seismic performance indicators were systematically studied. The experimental and theoretical analysis results show that the prestressed prestressed concrete beam-column assembly has strong energy dissipation capacity and can meet the requirements of seismic fortification. Due to the function of prestressing tendons, the residual deformation after unloading is small, and the recovery performance is better. The joint of beam and column is the key part of this node. After proper design, the necessary measures can be taken to improve its energy dissipation capacity.
