In high intensity zone, stiffness of strengthened story has significant influence on displacement of the structure and bearing capacity of relative members in seismic design, which becomes a key step in performancebased seismic design. The method of try and error is usually adopted while selecting the stiffness. In order to reduce the work and search a simple method for assessing the stiffness of this structure, stiffness harmonization of components considering displacement controlling based on stiffness analysis was discussed, a method of assessing stiffness and reasonable range of parameters were suggested. Lastly, as an example, this method was applied in the design of a concretefilled steel tube framecorewall structure with strengthened story. The result shows that the method is feasible for the design through elastic analysis, elastoplastic analysis and shakingtable test.Keywords:strengthened story; framecorewall hybrid structure; seismic design; stiffness作者簡(jiǎn)介:田淑明,博士,高級(jí)工程師,一級(jí)注冊(cè)結(jié)構(gòu)工程師,注冊(cè)土木工程師(巖土),Email: tianshm2011@163.com。參考文獻(xiàn)[1]徐培福,傅學(xué)怡,王翠坤,等. 復(fù)雜高層建筑結(jié)構(gòu)設(shè)計(jì)[M]. 北京:中國(guó)建筑工業(yè)出版社,2005.[2]聶建國(guó). 鋼\|混凝土組合結(jié)構(gòu)原理與實(shí)例[M]. 北京:科學(xué)出版社,2009.[3]汪大綏,周建龍. 我國(guó)高層建筑鋼\|混凝土混合結(jié)構(gòu)發(fā)展與展望[J]. 建筑結(jié)構(gòu)學(xué)報(bào),2010,31(6):6270.[4]王翠坤,田春雨,肖從真. 高層建筑中鋼混凝土混合結(jié)構(gòu)的研究及應(yīng)用進(jìn)展[J]. 建筑結(jié)構(gòu),2011,41(11):2833.[5]張令心,郭豐雨. 鋼混凝土混合結(jié)構(gòu)抗震研究評(píng)述[J]. 地震工程與工程振動(dòng),2004,24(3):5156.[6]Structural Engineering Association of California.
