摘　　要：通过对两个1:3的两边连接竖向加劲式钢板剪力墙试件进行低频往复循环加载,研究了结构的初始刚度、滞回性能、承载能力以及破坏机理等性能指标,从而对结构的抗震性能进行了评估.试验研究表明,两边连接竖向加劲式钢板剪力墙作为抗侧力构件承担了大部分侧向力,在弹性阶段产生了预期的屈曲破坏,主要表现为角部钢板的撕裂和鼓曲;在钢板墙破坏后期可以观察到在对角线方向形成了明显的拉力带.因此,非常适合在地震高烈度区进行推广.Two 1：3 two-side constraint steel plate shear wall specimens with vertical stiffeners were tested under low cyclic loading to study its seismic performance through the performance indexes of the initial stiffness, hysteretic behavior, load-carrying capacity, destruction mechanism and so on. Tests results showed that as main lateral force resisting members two-side constraint steel plate shear wall with vertical stiffeners had a very superior seismic performance. In the elastic phase destroyed expected buckling, mainly for the comer plate tearing and buckling failure, the diagonal direction formed apparent tension band can be observed in the steel plate wall destroyed later. So it is worth popularizing in the area of high seismic intensity.
