对2个矩形钢管混凝土框架-通高开洞加劲薄钢板剪力墙足尺试件和1个非开洞墙试件进行了低周往复水平荷载试验。试件设计考虑了边框柱承受轴压力、有无开洞及洞口位置的影响。研究得到了各试件的水平荷载-顶点位移滞回曲线和骨架曲线，在此基础上对试件的破坏模式、承载力、延性、耗能能力、刚度退化、强度退化等性能指标进行了分析。结果表明：在边框柱承受竖向压力的情况下，试件极限位移角达到1/51~1/29，试件具有良好的延性变形能力。与非开洞墙的斜拉带破坏方式有所不同，开洞墙的破坏始于洞口边缘加劲肋的破坏，边侧开洞试件保有一定的抗剪破坏特征，破坏形态属于弯剪破坏模式，中间开洞试件的破坏形态属于弯曲破坏模式。当洞口尺寸相同时，边侧开洞试件的性能要优于中间开洞试件。推覆分析结果表明，当边框柱的设计轴压比不大于0.7时，试件的塑性变形能力较好。最后建议洞口边缘加劲肋除了满足现行规范给出的刚度要求外，应按竖向受力构件进行承载力验算。对通高开洞钢板剪力墙按壳元建模，此时可仅验算墙体抗剪承载力，同时应对墙体周边竖向构件的轴力乘以1.10~1.15的放大系数。
Abstract
A low-cycle reversed horizontal load experimental research was conducted on two full-scale specimens of rectangular concrete filled steel tubular frame with full height opening stiffened thin steel plate shear walls (SPSW) and one non-opening SPSW specimen. The influence of the presence or absence of openings, and the opening positions was considered during the design of specimens. The frame columns were subjected to axial compression. The horizontal load-vertex displacement hysteresis curve and skeleton curve of each specimen are obtained through the study. On this basis, the failure mode, bearing capacity, ductility, energy dissipation capacity, stiffness degradation, strength degradation and other performance indicators of specimens were analyzed. The test results show that the specimens have good ductile deformation ability when the frame columns are subjected to vertical pressure. The ultimate drift ratio of the specimens can reach 1/51~1/29. Different from the failure mode of the non-opening wall, the failure of the opening wall starts from the failure of the stiffener at the edge of the opening. The side opening specimen retains certain shear failure characteristics, and the failure mode is the bending shear failure mode. The failure mode of the specimen with the middle opening is the bending failure mode. When the size of the opening is the same, the performance of the side opening specimen is better than that of the middle opening specimen. Finally, it is suggested that in addition to meeting the stiffness requirements given in the current code, the bearing capacity of the edge stiffeners should be checked as vertical members. The steel plate shear wall with full height opening is modeled by shell element. At this time, only the shear bearing capacity of the wall should be checked, and the axial force of the surrounding vertical members should be multiplied by 1.10~1.15.
