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)作者简介:许秀珍,高级工程师,一级注册结构工程师,Email:chnmaje@163.com。参考文献[1]程光煜,叶列平,许秀珍,等.防屈曲耗能钢支撑的试验研究[J]. 建筑结构学报, 2008,29(1):31-39.[2]程光煜,叶列平,崔鸿超. 防屈曲耗能钢支撑设计方法的研究[J]. 建筑结构学报, 2008,29(1):40-48.[3]周云. 防屈曲耗能支撑结构设计与应用[M]. 北京:中国建筑工业出版社,2007.
