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作者简介：罗志国，硕士，高级工程师，一级注册结构工程师，注册土木工程师（岩土），Email：lzg77@126.com。参考文献［1］曹万林，王敏，王绍合，等. 矩形钢管混凝土边框组合剪力墙及筒体结构抗震研究［J］. 工程力学，2008，25(6)：5870.［2］张莉华，万怡秀，陈燕，等. 广州珠江新城J11地块综合楼超高层建筑结构设计［J］. 建筑结构，2012,42(9):7074.
