摘　　要：为研究钢管混凝土边框与钢筋混凝土剪力墙结构竖向接合面的抗震性能,设计了4个接合面试件,并进行拟静力加载试验。试件破坏形式均相似,主要裂缝产生部位均在销键处,最终墙体形成贯通的斜裂缝。结果表明:接合面采用销键和连接筋的组合连接方式,可以保证接合面剪力的有效传递;连接筋的配筋率对结构的抗震有显著影响,在一定范围内,增加连接筋配筋率可以改善结构的抗震性能。To study the seismic performance of vertical joint that concrete filled steel tubular frame and reinforced concrete shear wall structure, four specimens are designed and tested with quasi-static loading program. The fail modes are similar that the main cracks appear in the key place, and in the end the diagonal cracks penetrated in the wall. The results show that： the vertical joint connected with a new combination connection that though pin keys and connecting bars guarantees the effective transfer of shear force; the reinforcement ratio effects the seismic structure significantly. Seismic performance of the structure will be improve as the increasing of reinforcement ratio within a certain range.
