Stressed behavior of top-seat angle steel beam-column connection under monotonic loading
【摘要】 运用ANSYS有限元软件,建立了顶底角钢梁柱连接节点的三维有限元模型,并对模型进行了非线性有限元分析,得到了顶底角钢梁柱连接节点的承载力和极限变形状态;深入分析了高强螺栓预紧力以及角钢与梁、柱间的接触压力等节点组件之间的力学特性,获得了试验难于测得的分析结果,可供工程设计参考。
【Abstract】 In order to study static mechanical properties of top-seat-angle steel beam-column connection,a 3D nonlinear finite element model was used to analyze the stressed behavior of top-seat-angle steel beam-column connection through the medium of finite element software ANSYS.Bearing capacity and ultimate deformation state of the top-seat angle steel beam-column connection as well as the mechanical properties which include prefastening force of high strength bolt and contact pressure between angle steel and beam/column were obtained.In which some of the result can not be obtained from test.The results can give a reference to engineering design of relative problem.
