摘　　要：通过5个框架内节点试件在低周反复荷载下的加载试验,对无黏结预应力装配式混凝土框架节点的破坏形态、滞回特性、变形恢复能力、位移延性、能量耗散等性能进行了研究．为建立该结构的抗震设计方法提供依据．结果表明,无黏结预应力装配式混凝土框架节点具有良好的抗震性能,在延性和变形恢复能力上比现浇框架节点更优．An experimental study on seismic performances of five beam-column connections subjected to reversed cyclic loading was conducted. These performances included failure pattern, hysteresis characteristics, displacement-restoring capacity, displacement ductility, and energy dissipation. The objective of the study is to develop guidelines for the design of precast prestressed concrete beam-to-column connection with unbonded tendons for regions of high seismicity. The study 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.
