摘要: 基于新型方钢管混凝土柱-钢梁节点的低周反复荷载试验,探讨了节点的受力机理,建立了节点弯矩传递模型,提出了节点抗弯承载力计算公式与相应的设计建议.Abstract: Based on the experimental results of a new type of joints between concrete-filled rectangular steel tubular columns and steel beams under cyclic loadings, stress patterns of the joint are analyzed, and a moment transferring model is created. A method for calculating the ultimate bearing moment and the corresponding suggestions for design are subsequently proposed.
