摘　　要：建立双腹板顶底角钢梁柱连接节点的精细有限元模型,对模型进行了非线性有限元数值计算,分析了在单调荷载作用下双腹板顶底角钢梁柱连接节点的承载力、极限变形状态、破坏机理和变形状态.深入探讨了双腹板顶底角钢梁柱连接高强螺栓的预紧力,角钢与梁、柱之间的接触压力等节点组件之间的力学特性,获得试验难于测得的力学特性,为双腹板顶底角钢梁柱连接在工程中的应用提供理论依据.The fine finite element model was set up for top and seat angle with double web angles steel beam-column connection and the nonlinear finite element calculation on the model was carried out,then the bearing capacity,ultimate deformation status,failure mechanism and deformetion status of top and seat angle with deuble web angles steel beam-column connection under monotonic loading were analyzed.The pre-tightening force of high-strength bolts connecting with the top and seat angle with double web angles steel beam-column was deeply discussed as well as the mechanical behavior of contact pressures between angle steel and beam-column.In this way,the mechanical properties were obtain,which was difficult to achieve by stets and provided a theoretical basis for the top and seat angle with double web angles steel beam-column connection applying in projects.
