摘要
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 SAP2000 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 （A） 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.
