文章通过SAP2000程序，建立了半刚性组合节点理论分析模型，采用转动弹簧单元来模拟实际中钢管柱与组合梁的半刚性连接。通过分析比较节点在低周反复荷载作用下的荷载（ P）－位移（Δ）关系滞回曲得到，组合节点的承载力、刚度和耗能能力有所提高，耗能较好，但承载力相差不大，所以在正常的施工条件下，应优先选用方钢管。

In this paper , the finite element analysis of SAP 2000 software is used to simulate the semi -rigid steel tube concrete com-posite joints.Simulated semi-rigid concrete filled steel tubular joint under low cycle repeated load load (P) -displacement (Δ) lag relationship back to the model , the bearing capacity , stiffness and energy dissipation capacity of the composite joints have been im -proved, but the load capacity is good , but the bearing capacity is different, so in the normal construction condition , it should be pre-ferred.
