摘　　要：通过三个框架节点在低周反复荷载下的试验,对无粘结预应力装配式混凝土框架连接的破坏形态、滞回曲线、变形恢复能力、位移延性、能量耗散等性能进行了研究。结果表明,无粘结预应力装配式混凝土框架连接具有良好的耗能能力,在延性和变形恢复能力上比现浇连接更优。Based on tests of three moment-resisting beam-column connections under low reversed cyclic loading, this paper inquires into the failure pattern, hysteresis loop curves, displacement-restoring capacity, displacement ductility and energy dissipation of the precast prestressed beam-to-column concrete connections with unbonded tendons. The results show that the performances of precast prestressed beam-to-column concrete connections with unbonded tendons are equal or superior to that of a monolithic connection in terms of ductility and displacement - restoring capacity.
