［摘要］為研究帶預制混凝土（PC）填充墻的裝配式聯(lián)肢剪力墻結(jié)構(gòu)抗震性能，完成1個無填充墻試件和2個帶PC填充墻試件的擬靜力試驗，考察試件在不同連接方式下的開裂與破壞形態(tài)、滯回曲線、承載力、剛度、延性和耗能等性能。結(jié)果表明：無填充墻試件和柔性連接試件的滯回曲線飽滿，表現(xiàn)出良好的耗能能力； 剛性連接試件的滯回曲線捏縮現(xiàn)象較為明顯，耗能能力較差； PC填充墻的存在可提高結(jié)構(gòu)的承載力、剛度，但降低了結(jié)構(gòu)的延性性能。采用推薦的剛性連接時，建議周期折減系數(shù)取0.8～1； 而采用柔性連接時，可參考砌塊填充墻周期折減系數(shù)取0.9～1。在實際工程中，建議根據(jù)PC填充墻的位置和數(shù)量，采用合理的周期折減系數(shù)。

Abstract:In order to study the seismic behavior of precast concrete coupled shear wall with PC infill wall, pseudo-static tests of one coupled shear wall without infill wall and two coupled shear walls with PC infill wall were carried out. Performance of the test specimens were inspected in terms of crack and failure mode, hysteretic curves, bearing capacity, stiffness, ductility and energy consumption capacity, etc. The test results show that: the hysteresis curves of specimen without infill wall and flexible connection specimen are full, showing good seismic performance. The pinching phenomenon of the hysteresis curve of rigid connection specimen is more pronounced and the energy dissipation capacity is poor. The presence of PC infill walls can improve the bearing capacity, stiffness, but it reduces the ductility of the structure. When using the rigid connection recommended, the period reduction factor is recommended to be 0.8～1, and when using the flexible connection, it can refer to the block infill wall period reduction factor of 0.9～1. In actual engineering, it is recommended to use a reasonable period reduction factor based on the location and number of PC infill walls.
