中文摘要：

对2个单跨两层1：3比例的方钢管混凝土框架-薄钢板剪力墙试件进行了低周反复荷载试验,研究了斜十字加劲薄钢板剪力墙的抗震性能,并与方钢管混凝土框架-非加劲薄钢板剪力墙进行比较.得到了方钢管混凝土框架-薄钢板剪力墙的荷载-位移滞回曲线、骨架曲线、特征荷载和位移及抗震性能指标,分析了结构的破坏特征、延性、耗能能力、承载能力及刚度退化等力学性能.结果表明,方钢管混凝土框架-薄钢板剪力墙具有较高的侧向刚度和承载力,良好的延性及耗能性能;斜十字加劲肋的设置提高了薄钢板剪力墙的强度和刚度,有效抑制了钢板墙的面外变形.方钢管混凝土竖向边缘构件保证了薄钢板剪力墙性能的充分发挥.

英文摘要：

This paper presents the results of a research conducted on two 1/3 scaled one bay-two story test specimens designed as thin steel plate shear walls（SPSWs） within steel frames with concrete-filled square tube columns as their VBEs.One of the specimens is diagonally stiffened and the other one is an un-stiffened steel plate shear wall.Test is performed under cyclic quasi-static loading.The curves that characterize the structure＇s seismic behavior are obtained including the displacement-loading hysteretic curves and skeleton curves.According to these curves,the failure patterns,ductility,energy dissipation,bearing capacity and degeneration of stiffness of this type structure were all analyzed in this paper.Experimental results show that the thin steel plate shear walls within steel frame with concrete-filled square tube columns exhibit high initial stiffness,behave in a ductile manner and dissipate significant amounts of hysteric energy.The diagonal stiffeners improve the stiffness of the structure and bearing capacity and these also reduce the out-of plane deflection.The VBEs made by concrete-filled square tube can provide sufficient rigidity to make sure the full use of the SPSWs.
