摘　　要：为研究钢筋混凝土框架-钢板剪力墙抗震性能,对一榀单跨两层的钢筋混凝土纯框架和一榀单跨两层的钢筋混凝土框架-钢板剪力墙进行低周往复加载试验,比较两者的破坏形态并分析原因。研究结果表明:钢筋混凝土框架-钢板剪力墙的承载力较钢筋混凝土纯框架提高77.2%,初始刚度为钢筋混凝土纯框架的2.67倍;非加载端梁、柱应变值较大,加钢板的混凝土框架节点转角变化量不大,破坏也相对较轻。建议通过加钢板来提高钢筋混凝土框架的承载性能及抗震性能。In order to study the seismic performance of reinforced concrete frame-steel plate shear wall,a low-cycle load test was carried out on a reinforced concrete frame with a single span two lagers and a reinforced concrete frame-steel plate shear wall with a single span two layers.The from and reason of the failure of the two structures was analyzed.The results show that the load-bearing capacity of reinforced concrete frame-steel plate shear wall is 77.2%higher than that of reinforced concrete frame,and the initial stiffness is 2.67 times that of reinforced concrete frame.The non-loading end beam and the column strain value are larger,the change of the rotation angle of the concrete frame node with steel plate is small,and the damage is relatively light.It is recommended to increase the bearing performance and seismic performance of reinforced concrete frame by adding steel plate.
