摘　　要：为研究传统风格建筑型钢混凝土(SRC)方柱-钢筋混凝土(RC)圆柱连接的基本抗震行为,设计了2个该类型柱连接的足尺模型试件,并对不同轴压比下的试件进行低周反复加载试验。结果表明:传统风格建筑SRC方柱-RC圆柱连接的破坏形态为典型的弯曲破坏,其抗震性能良好。破坏时SRC柱根部的型钢、箍筋和纵筋可以达到屈服,轴压比对试件的破坏形态具有重要的控制作用。根据测试结果及对试件加载过程中荷载-位移关系分析,得到了传统风格建筑SRC方柱-RC圆柱连接弹性侧移刚度的统计回归计算式,计算值与试验值吻合较好。Two full scale specimens of connection between steel reinforced concrete（ SRC） square column and reinforced concrete（ RC） circular column in traditional style building were designed in order to research the failure modes and seismic performance of this type of specimen. According to the quasi-static test of the specimens under different axial compression ratio,the results showed that the failure mode of connection between steel reinforced concrete square column and reinforced concrete circular column in traditional style building was typical bending failure and it had perfect seismic performance. The steel,stirrups and longitudinal reinforcement could reach yield when the SRC column was broken and the axial compression ratio played an important role in controlling the failure mode of the specimen. The calculation of the elastic lateral displacement stiffness of specimen was obtained by the results of the test and analysis of load-displacement relationship during the test loading. The calculated values were in good agreement with the experimental values.
