以适用于小高层建筑的钢框架短肢组合钢板剪力墙结构初步试验结果为基础，遴选出以角钢和面外墙板共同约束的组合剪力墙结构．以该型组合剪力墙结构为研究对象，针对内嵌钢板宽厚比、面外墙板约束、钢板边界约束3 个因素进行了优化分析，并对优化后的结构进行了低周往复加载试验．结果表明，合理优化该型组合剪力墙结构可有效提高结构整体的抗震耗能能力，在模型整体高度和跨度相同的情况下，滞回曲线更加饱满，延性比提高约7. 7%，弹性抗侧刚度提高约49%，耗能能力提高约62%．

In this paper,by analyzing the early-obtained preliminary experiment results of the composite steel-plate shear wall system with short-limb steel frame applied to mid-rise buildings,the composite shear wall constrained by angle steel and external precast concrete wallboard was selected as the research objective to further optimize the width-to-thickness ratio of the embedded steel plate as well as the boundary constraints of the external wallboard and of the steel plate. Moreover,some low-cyclic tests were carried out for the optimized structure. The results indicate that the shear wall system with proper structure can effectively improve the energy dissipation ability; and that,at the same height and span,the hysteresis curve of the system becomes fuller,and the ductility ratio.the elastic lateral stiffness,and the energy dissipation ability increase by about 7. 7%,49% and 62%,respectively.
