摘　　要： 为研究多高层预制混凝土结构的抗震性能,选取某住宅楼的典型节点进行试验研究,并采用足尺模型试验方法,对结构底部高轴压、大尺寸的预制梁-柱-叠合板装配边节点试件在低周反复荷载作用下的开裂破坏形态、滞回特性、骨架曲线、延性性能、耗能能力、拼缝等进行研究,结果表明:对于此类连接装配式混凝土框架边节点与整体现浇节点具有相当的抗震性能。 In order to analyze the seismic behavior of multi-story precast concrete structures,experimental study was conducted for some typical joints of an apartment building.With full-scale models,the seismic behavior of precast layered slab and beam to column exterior joints was investigated under high axial loading and low-cycle reversed loading.The failure pattern,hysteretic characteristics,skeleton curve,ductility,energy dissipation and abutted seam,were analyzed.The results indicated that the earthquake resistance performance of this type of connection is almost equal to that of monolithic connections.
