摘要
本文提出一种新型装配式混凝土梁柱节点,进行该新型节点与普通现浇混凝土梁柱节点的拟静力试验,对比3个构件的试验现象、滞回性能、刚度退化、耗能能力等抗震性能指标。研究结果表明,与普通现浇混凝土梁柱节点相比,采用钢节点板连接的装配式混凝土梁柱节点的滞回性能、耗能能力、极限承载力均得到了有效的提高,节点的刚度退化得以延缓。预制柱端板外移的连接方式比端板置于柱端的连接方式能较好地改善装配式混凝土梁柱节点的破坏形态和滞回性能。
A new type of prefabricated concrete joint is proposed in this paper,the quasi-static test of this new type of joint and ordinary cast-in-situ concrete beam-column joint is carried out,and the seismic performance indexes such as test phenomenon,hysteretic behavior,stiffness degradation and energy dissipation capacity of the three specimens are compared. The results show that compared with ordinary cast-in-situ concrete beam-column joints,the hysteretic behavior,energy dissipation capacity and ultimate bearing capacity of prefabricated concrete beamcolumn joints connected by steel plate connectors are improved effectively,and the stiffness degradation of joints is delayed. Compared with the precast column end plate which is placed at column end,the failure mode and hysteretic performance of prefabricated concrete beam-column joint,which precast column end plate is outward from the column,is better.
