摘　　要：为研究双肢钢板剪力墙的抗震性能,利用ABAQUS有限元分析软件对低周往复荷载作用下内填板高厚比、高宽比以及中部连梁跨度对结构滞回性能的影响进行分析,并给出各自的滞回曲线。另外,通过骨架曲线分析3个参数对结构极限承载力、抗侧刚度及延性的影响。分析结果表明:内填板高厚比和高宽比对结构的滞回性能具有较大的影响,而中部连梁的跨度则影响较小。To validate the seismic performance of a coupled steel plate shear wall（C-SPSW）,hysteretic behavior of C-SPSW structures under low cyclic loads with different height to thickness ratio,depth to width ratio and the central beam span are analyzed with the general finite element analysis software ABAQUS,and each hysteresis curve are given.What＇s more,influence of the three parameters on ultimate bearing capacity,lateral stiffness and ductility are analyzed with the hysteresis skeleton curves.The analysis results show that the height to thickness ratio and depth to width ratio have significant impact on the ultimate bearing capacity of the C-SPSW structures, while the effect of the central span beam is little.
