摘　　要：为研究带预制混凝土(PC)填充墙的装配式联肢剪力墙结构抗震性能,完成1个无填充墙试件和2个带PC填充墙试件的拟静力试验,考察试件在不同连接方式下的开裂与破坏形态、滞回曲线、承载力、刚度、延性和耗能等性能。结果表明:无填充墙试件和柔性连接试件的滞回曲线饱满,表现出良好的耗能能力;刚性连接试件的滞回曲线捏缩现象较为明显,耗能能力较差;PC填充墙的存在可提高结构的承载力、刚度,但降低了结构的延性性能。采用推荐的刚性连接时,建议周期折减系数取0.8~1;而采用柔性连接时,可参考砌块填充墙周期折减系数取0.9~1。在实际工程中,建议根据PC填充墙的位置和数量,采用合理的周期折减系数。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.
