摘　　要：两边连接竖向加劲钢板剪力墙是一种新型的结构形式.为了探讨钢板墙与钢框架的协同作用机理,寻求钢板墙、梁、柱合理的刚度匹配,对钢板剪力墙布置位置不同的两个1∶3的三层三跨试件进行低周往复循环加载,观察和总结结构的协同作用机理;通过屈服点、极值点、延性系数、滞回曲线、骨架曲线、能量耗散系数、割线刚度等力学性能指标衡量其抗震性能,并且比较了钢板墙分布位置对结构的影响.试验证明,这种新型的结构形式有着优越的抗震性能,特别适合在地震高烈度区进行推广.The vertically stiffened steel plate shear wall（SPSW） with two-side constraints is a kind of new structural form.To reveal the synergistic effect mechanism between steel frame and wall,and then look for reasonable stiffness match between the steel walls,beams and columns,two three-bay three-story models（1∶ 3 scale） were studied experimentally under cyclic quasi-static loading.The component failure mechanisms were summarized.Besides,the influences of different SPSW layouts on the structural system were investigated.The results show that the vertically stiffened SPSW with two-side constraints has better seismic performance,and such structural form is particularly suitable for areas with high seismic intensity.
