Located in the 8 degree earthquake zones, steel frame-core wall structure with the good ductility was adopted in the design with the first application of buckling restrained braces in China. Performance of the buckling restrained braces was studied and the whole structure was analyzed.Keywords: steel structure; frame-core wall structure; eccentric brace; buckling restrained brace (BRB)作者簡介:許秀珍,高級工程師,一級注冊結(jié)構(gòu)工程師,Email:chnmaje@163.com。參考文獻(xiàn)[1]程光煜,葉列平,許秀珍,等.防屈曲耗能鋼支撐的試驗(yàn)研究[J]. 建筑結(jié)構(gòu)學(xué)報(bào), 2008,29(1):31-39.[2]程光煜,葉列平,崔鴻超. 防屈曲耗能鋼支撐設(shè)計(jì)方法的研究[J]. 建筑結(jié)構(gòu)學(xué)報(bào), 2008,29(1):40-48.[3]周云. 防屈曲耗能支撐結(jié)構(gòu)設(shè)計(jì)與應(yīng)用[M]. 北京:中國建筑工業(yè)出版社,2007.
