摘　　要：本文从钢管混凝土梁柱节点的梁、柱及节点区域的变形及其弯矩———转角恢复力模型与出发,建立了分析梁端荷载———位移滞回曲线与弯矩———转角滞回曲线的简化计算模型,利用Matlab编制相应的计算程序,计算结果吻合于实测结果。此类简化分析有助于组合结构节点设计与工程应用。In this paper, the simplified calculation model was established, based on the deformation and moment-rotation framework curves of the beam, the column and the joint area. The model was used to predict the load-displacement behavior and moment-rotation characteristics of the CFT column to beam steel connection under low-cycle reversed loading. The procedure was implemented by Matlab program. The results from the simplified calculation model correct well with that from testing. This kind of simplified analysi...
