摘　　要：通过加固拟静力试验后受损的装配式框架节点,评估了新型预应力钢丝绳加固法在装配式框架抗震加固中的应用效果。试验结果表明:预应力钢丝绳加固法的施工工艺简单,关键部件可在工厂预制批量生产,加固效率显著提高。预应力钢丝绳加固后的受损装配式框架在滞回曲线、骨架曲线、刚度退化、耗能能力、残余变形等关键指标上均展现出良好的性能,特别是在增强结构的刚度和承载力方面表现突出。In this paper,the application effect of the new prestressed wire rope reinforcement method in the seismic reinforcement of the prefabricated frame is evaluated by strengthening the joints damaged after the pseudo-static test.The test results show that the construction process of the prestressed steel wire rope reinforcement method is simple,and the key components can be mass-produced in the factory,and the reinforcement efficiency is significantly improved.The prestressed steel wire rope reinforced damaged prefabricated frame shows good performance in hysteretic curve,skeleton curve,stiffness degradation,energy dissipation capacity,residual deformation and other key indexes,especially in strengthening the stiffness and bearing capacity of the structure.
