【摘要】 通过对双腹板顶底角钢梁柱连接原型模型进行循环荷载的试验研究,并对试验模型进行非线性有限元分析计算,全面分析了双腹板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,预紧力的变化对节点组件工作影响最大,对工程设计有重要的参考价值。更多还原

【Abstract】 The hysteretic behavior of the beam-column connections with top-seat and web angles under cyclic loading was presented,and the simulation model of top-seat and web angles connections was set up by using ANSYS.The failure mechanism and ultimate deformation of top-seat and web angles beam-column connections was analyzed.The preload of bolt and the mechanical properties of the contact pressure of the components were researched.The component mechanical property is mostly impacted by the preload.更多还原
