Abstract

Steel plate shear walls (SPSWs) are efficient options for lateral load-resisting systems in buildings. However, introducing opening(s) in the SPSWs results in a significant drop in their performance. To investigate the effects of introducing openings and adding stiffeners around them on the performance of SPSWs, thirty-three finite element-based models of stiffened SPSWs with full height opening were analyzed. These models had different steel plate thicknesses, opening aspect ratios, and stiffener configurations. Numerical results of this study agreed with the Plate-Frame Interaction (PFI) theory. It was found that adding stiffeners considerably increased shear stiffness and shear strength of SPSW. Furthermore, improvement in the shear load carrying capacity of the SPSW is significantly influenced by cross-sectional shape and even arrangement of the stiffeners. Finally, it was shown that SPSWs with a thicker steel plate are more sensitive to both the presence of the opening and its widening.

全高开口钢板剪力墙和不同配置加劲件的抗剪行为数值研究

钢板剪力墙（SPSW）是建筑物抗侧载系统的有效选择。然而，在钢板剪力墙中引入开口会导致其性能显著下降。为了研究引入开口并在其周围添加加劲件对 SPSW 性能的影响，我们分析了 33 个基于有限元的全高开口加劲 SPSW 模型。这些模型具有不同的钢板厚度、开口长宽比和加劲件配置。研究的数值结果与板框相互作用（PFI）理论一致。研究发现，增加加强筋可显著提高 SPSW 的剪切刚度和剪切强度。此外，加强筋的横截面形状和均匀排列对提高 SPSW 的剪切承载能力有显著影响。最后，研究表明，钢板较厚的 SPSW 对开口的存在和扩大更为敏感。
