Mechanical behaviors of composite walls were investigated from the three aspects of elastic\|static analysis,elasticplastic finite element analysis and model experiments. The loadbearing capacity,ductility,stiffness and degradation,hysteretic property,energy dissipation capacity and failure characteristics were analyzed. Results show that this kind of composite wall combines advantages of strong lateral stiffness and large capacity of concrete shear walls and good seismic behavior of concrete filled steel tube columns. Shear connectors connecting concrete filled steel tube columns and concrete shear walls work well. This kind of composite wall is well applied in engineering.Keywords:CFT-CW composite wall; shear connector; concrete filled rectangular steel tube; seismic behavior作者簡(jiǎn)介：羅志國(guó)，碩士，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：lzg77@126.com。參考文獻(xiàn)［1］曹萬(wàn)林，王敏，王紹合，等. 矩形鋼管混凝土邊框組合剪力墻及筒體結(jié)構(gòu)抗震研究［J］. 工程力學(xué)，2008，25(6)：5870.［2］張莉華，萬(wàn)怡秀，陳燕，等. 廣州珠江新城J11地塊綜合樓超高層建筑結(jié)構(gòu)設(shè)計(jì)［J］. 建筑結(jié)構(gòu)，2012,42(9):7074.
