摘　　要：文章介绍了分阶段屈服装配式混合连接节点的构造并进行了试件设计以及建模过程中钢筋混凝土本构和梁柱单元的选择,对董挺峰的混合连接节点加以改造建立了分阶段屈服混合连接节点模型。通过数值模拟及结果分析,分阶段屈服装配式混合连接节点能有效控制地震时梁柱接触面的转角变形过大的问题,从而使装配式结构具有良好的抗震性能。This paper introduces the construction of the staged flex-fitted hybrid joints and the selection of reinforced concrete constitutive and beam-column elements in the design and modeling process of the specimens,and the transformation of the mixed joints of Dong Tingfeng to establish a staged yield hybrid connection model.Through numerical simulation and result analysis,the staged flexing assembled hybrid joint node can effectively control the problem of excessive corner deformation of the beam-column contact surface during earthquake,so that the fabricated structure has good seismic performance.
