摘要

摘要: 为了提供一种适用于高烈度抗震设防区的装配结构连接方式,并为建立该结构的抗震设计方法提供依据,通过6个混合连接装配式混凝土框架内节点试件在低周反复荷载下的加载试验,对其破坏形态、滞回特性、变形恢复能力、位移延性、能量耗散等进行了研究。结果表明,混合连接装配式混凝土框架节点的耗能能力与整体现浇混凝土节点相当,而其延性和变形恢复能力则优于整体现浇混凝土节点,其综合抗震性能优于整体现浇混凝土节点。

Abstract: An experimental study on seismic performances of six hybrid precast beam-to-column concrete connections subject to reversed cyclic loading was conducted.The study includes failure pattern,hysteresis characteristics,displacement-restoring capacity,displacement ductility,and energy dissipation.The objective of the study is to present a kind of precast frame structure that is suitable for regions of high seismicity and to develop guidelines for the structure design.The study results show that the energy-dissipating capacity of the hybrid connection is almost equal to that of the monolithic connection,while the displacement ductility and displacement-restoring capacity of the hybrid connection is superior to that of the monolithic connection,and the overall seismic performance of the hybrid connections is superior to that of the monolithic connection.
