摘　　要：采用组件法建立了能够反映贯通式梁-柱端板连接节点滞回性能的数值分析模型。模型中考虑了包括梁腹板、梁翼缘、端板及端板加劲肋在内的基本组件对节点滞回性能的影响。通过ABAQUS软件实现了无端板加劲肋和有端板加劲肋两种不同构造形式下的组件法模型的计算。组件法计算结果与实体单元模型计算结果基本吻合,证明了组件法模型可以用来预测贯通式梁-柱端板连接节点在往复荷载下的力学行为。In this paper,based on the component method,the mechanical models are established for simulating the behavior of end-plate joints with continuous beam and column under cyclic loads.These mechanical models are composed of basic components,including beam web in shear,beam flange in bending,end-plate in bending and end-plate stiffener in axial load,which are modeled as spring elements in order to simulate their various response mechanisms interacting each other in the connections.Two types of connections,non-stiffened end-plate connection and stiffened end-plate connection,are studied,and the computational models are built using finite element software ABAQUS.The accuracy of the component method models is proved by a comparison with the analysis results of entity element models.Finally,the mechanical models established in this study can predict the response of the end-plate joints with continuous beam and column under cyclic loads.
