摘　　要：防屈曲钢板墙(简称BRSPSW)是一种适用于高层钢结构的新型抗侧力构件,具有塑性性能好、滞回特性稳定、可独立变化墙板承载力和刚度以及布置灵活等优点,可克服支撑框架易受建筑功能限制的缺点。以某34层钢结构住宅为背景,首先提出BRSPSW适用性布置方式,并对其进行比选分析。然后基于结构弹性层间位移角要求,通过6组算例对D形布置BRSPSW跨越门洞传力转换进行了分析,提出了有效高宽比概念与BRSPSW体系方案设计阶段参考建议。Buckling-restrained steel plate shear wall（BRSPSW）is a new type of lateral force resisting component suitable for high-rise steel structures.BRSPSW has a good plastic performance and stable hysteretic characteristics,and its bearing capacity and stiffness can be individually adjusted.Also,unlike braces,BRSPSWs can be applied at various locations of the structures without being limited by architectural functions.This paper presents an application of BRSPSW in a 34-story high-rise steel residential structure.Based on the elastic inter-story drift requirement,the force transfer is analyzed through six examples on D-shape arrangement of BRSPSW across the doorway.The concept of effective aspect ratio is proposed and design recommendations for BRSPSW system in overall design phase are proposed.
