摘　　要：对方钢管混凝土柱与钢筋混凝土梁连接的半连通芯钢管节点在低周反复荷载作用下的受力性能进行有限元分析。分析结果显示,节点核心区内芯钢管及环箍对节点强度的补充,使得该节点具有较好的强度和延性。由滞回性能分析可知,该类节点的滞回曲线呈纺锤形,具有较好的耗能能力。The study explores finite element analysis of low cyclic reversed loading of the interior joints with core steel tube in concrete filled square steel tube. The results show that the core steel tube and the hoop are the supplement to the joint strength,which make the joints have high strength and ductility.According to the hysteretic property analysis,the hysteretic curve of the joint shapes in fusiform,which means that it has good energy dissipation capacity.
