摘　　要：新型装配式剪力墙结构为底部竖向分布钢筋断开、水平部分开缝的一种剪力墙结构,具有施工便捷、施工质量易于控制等优点。为了研究地震荷载作用下竖向分布钢筋不连接装配式剪力墙的承载力、延性、刚度及耗能等抗震性能,进行足尺现浇剪力墙和装配式剪力墙试件的低周反复荷载试验。介绍了两种剪力墙试件的破坏形态,分析研究了剪力墙试件的滞回曲线、骨架曲线、位移延性、刚度退化及耗能能力等。试验结果表明:竖向分布钢筋不连接的装配式剪力墙在承载能力、耗能能力等方面弱于现浇剪力墙,刚度退化与现浇剪力墙基本一致;装配式剪力墙滞回曲线饱满,结构层间位移角未超过规范限值1/120,满足抗震性能目标的要求;增大轴压比可显著提高装配式剪力墙试件的承载能力、位移延性及刚度。The new prefabricated shear wall structure is a type of shear wall structure in which the vertically distributed reinforcement at the bottom is disconnected and the horizontal part is slotted.It has the advantages of convenient construction and easy quality control.In order to study the bearing capacity,ductility,stiffness and energy dissipation of prefabricated shear wall with vertically distributed reinforcement under seismic load,low cyclic loading tests of full⁃scale cast⁃in⁃situ shear walls and prefabricated shear wall were carried out.The failure modes of shear wall specimens were described in detail,and the hysteretic curve,skeleton curve,displacement ductility,stiffness degradation and energy dissipation capacity of shear wall specimens were analyzed and studied.The test results show that the prefabricated shear wall without vertical distribution reinforcement is weaker than the cast⁃in⁃situ shear wall in bearing capacity and energy dissipation capacity,and the stiffness degradation is basically the same as that of the cast⁃in⁃situ shear wall.The hysteretic curve of the fabricated shear wall is full,and the inter story displacement angle of the structure does not exceed the code limit value of 1/120,meeting the requirements of the seismic performance target.Increasing the axial compression ratio will significantly improve the bearing capacity,displacement ductility and stiffness of prefabricated shear wall specimens.
