摘　　要：提出了基于压杆模型和软化桁架模型的钢筋混凝土梁柱节点抗震设计方法.计算发现,压杆模型或软化桁架模型所分配到的外荷载并不平衡.通过编程计算解决了外荷载在这两个模型间分配的问题.通过3个钢筋混凝土梁柱外节点试验数据验证了该设计方法的可靠性.A seismic resistant design method of reinforced concrete beam-column connections based on compression strut and softened truss models was proposed. The calculation results revealed that the loads carried by the compression strut or the softened truss model were not in equilibrium. The issue, assigning the loads between the two models, was solved by a program made by authors. The reliability of the proposed design method was verified by test data of three reinforced concrete beam-column exterior connections.
