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作者簡介：沈金，博士，研究員，一級注冊結(jié)構(gòu)工程師，Email:shenj@zuad.com。參考文獻(xiàn)［1］干鋼，沈金，童根樹. 巨型成對單斜支撐鋼結(jié)構(gòu)體系設(shè)計(jì)研究［J］. 建筑結(jié)構(gòu)， 2013， 43（15）：15-18,22.［2］JGJ 99—2013高層民用建筑鋼結(jié)構(gòu)技術(shù)規(guī)程(報批稿)［S］.［2］GB 50011—2010 建筑抗震設(shè)計(jì)規(guī)范［S］. 北京:中國建筑工業(yè)出版社, 2010.
