摘　　要：为研究预制装配式竖缝剪力墙的抗震性能,利用低周反复荷载试验对预制装配式竖缝剪力墙进行了研究,得到试件的滞回曲线。分析了预制装配式竖缝剪力墙的破坏形态、裂缝行为、荷载-位移关系、裂荷载、抗剪承载力以及变形特性的发展规律。综合考察该装配式剪力墙结构的破坏模式和变形能力。试验结果表明:预制装配式竖缝剪力墙在水平地震作用下的破坏模式属于延性破坏,耗能性能较好;竖缝墙由缝间墙受弯破坏终发展成贯通各墙肢竖缝根部的剪切破坏;剪力墙与基础梁间的钢板连接件未发生破坏,能提供有效连接。To investigate the seismic behavior of the precast slotted shear wall,low cyclic loading experimental was made. On the basis of tests,failure patterns,crack behaviors,loading-displacement relation,crack load,shear capacity as well as deformation characteristic of specimen shear wall were studied in detail. The results indicate that the failure mode of precast slotted shear is ductile failure under earthquake energy and has good energy performance. The failure pattern of shear wall was bending failure at first then developed into shear failure at last with crack run through the whole shear wall. The steel plate connection between the shear wall and foundation beams had no failure,which showed that the connection was reliable.
