［摘要］介绍钢板剪力墙在具体实际工程中的应用，为了给核心区域电梯门厅通道留出尽可能宽的通道而将原先设计的钢支撑修改为钢板剪力墙，总宽度从800mm减小到340mm，增加了电梯厅走廊的宽度。设计采用将钢支撑等效为钢板剪力墙的方法，给出了不同厚度钢板剪力墙的闭口单面加劲肋的尺寸及其间距。针对钢板剪力墙承担竖向荷载时的应力分析，提出了考虑竖向应力后钢板剪力墙剩余抗剪承载力的计算方法。

Abstract: A practical application of steel shear walls is introduced. In order to keep as large as possible space for the elevator corridor, steel shear walls were used to replace the original steel diagonal bracing, the total width of the members is reduced from 800mm to 340mm, and the width of the corridor is increased. The procedure by which the diagonal bracings are equivalently converted into stiffened steel shear walls is introduced, the sizes of closed form stiffeners and the required distance between stiffeners are also presented for reference. The stress analysis of steel wall is introduced under gravity loads, and proposed a method for determining the effective load-carrying capacity for shear.

Keywords: steel shear wall; shear buckling; seismic design; high-rise building; steel structure
