摘　　要：利用ANSYS软件分析了套筒式钢管混凝土梁柱节点的承载性能,同时进行了采用力位移混合加载控制的节点承载力低周反复荷载试验。结果表明,套筒式节点和环板式节点的极限受弯承载力都能满足设计要求,但套筒式节点的转角较小,节点为刚性连接。在相同的轴压比下,两种形式节点的抗震性能相当。The software ANSYS is used to calculate the bearing performance of concrete filled steel tubular column to beam connection using sleeve, and the low cycle loading tests of the connections are conducted. The results show the limited bending capacities of the concrete filled steel tubular column to steel beam connections using sleeve and using ring board can meet the design requirement but the rotation of the former is lower and the connection is rigid. Under the same axial compression ratio, the seismic performances of the two kinds of the connections are nearly the same.
