摘　　要：通过对顶底角钢梁柱连接原型模型进行循环荷载作用下的试验研究,以及对试验模型进行非线性有限元分析计算,全面分析了顶底角钢梁柱连接节点在循环荷载作用下的破坏机理和极限变形状态,研究了高强螺栓预紧力,角钢与梁、柱之间的接触压力等节点组件之间的力学特征,对工程设计有重要的参考价值。The hysteretic behavior of top-seat-angle steel beam-column connections under cyclic loading is presented and full-scale model of top-seat-angle steel connections is analyzed by using ANSYS.The failure mechanism and ultimate deformation of top-seat-angle steel beam-column connections are analyzed.Then the preload of bolt,the contact pressure of components and the mechanical properties between other components of the connections are studied.These results can provide good reference for the engineering design.
