Despite the many advantages of steel shear walls, such as high strength and stiffness, good ductility and high energy dissipation, the increase in the size of columns next to the steel shear walls is a drawback that affects the use of this system. In order to achieve an economic design while keeping design essentials and optimal performance, a novel steel shear wall system called “semi-supported steel shear wall (SSSW)” was proposed, in which the wall plate is attached to the secondary columns instead of the primary columns of the frame. The secondary columns are only responsible for creating the tension field in the plate and the lateral load rather than partnership in the toleration of gravity loads. In this paper, due to the lack of knowledge on the dynamic behavior of steel plate shear walls in general and SSSW in particular, the nonlinear dynamic behavior of SSSWs is investigated. The explicit finite element method is used for analysis and the results are verified by the laboratory test results. The results of the nonlinear dynamic analysis show that semi-supported shear walls have a very good dynamic performance in increasing stiffness and reducing the lateral displacement of the structure. The effects of various parameters of SSSW on its dynamic behavior are also investigated.

尽管钢剪力墙具有高强度和刚度、良好的延性和高耗能等许多优点，但钢剪力墙旁边柱尺寸的增加是影响该系统使用的一个缺点。为了实现经济设计，同时保持设计要点和最佳性能，提出了一种称为“半支撑钢剪力墙（SSSW）”的新型钢剪力墙系统，其中墙板附着在次柱上，而不是附着在次柱上。框架的主柱。次柱仅负责在板中产生张力场和横向荷载，而不负责承受重力荷载。在本文中，由于缺乏对钢板剪力墙尤其是SSSW的动力行为的了解，因此对SSSW的非线性动力行为进行了研究。采用显式有限元方法进行分析，并通过实验室试验结果进行验证。非线性动力分析结果表明，半支撑剪力墙在增加结构刚度、减少结构侧向位移方面具有很好的动力性能。还研究了 SSSW 的各种参数对其动态行为的影响。
