| 摘 要： | 利用有限元分析软件ANSYS对单腹板角钢连接、双腹板角钢连接、顶底角钢连接、带双腹板的顶底角钢连接四种不同连接方式的钢框架进行非线性有限元分析。采用Kishi-Chen幂函数模型和COMBIN 39单元模拟半刚性连接的非线性行为。通过比较四种不同连接方式钢框架的滞回曲线,探讨半刚性连接方式对钢框架耗能能力的影响,为半刚性连接钢框架的设计提供参考。

| Abstract: | Using finite element analysis software(ANSYS) to make nonlinear finite element analyse for four different types which are the single web angle connections,the double web angle connections,the top-and-seat angle connections and the top-and-seat angle with double web-angle connections.Kishi-Chen Power Function Model and Nonlinear Spring Elements(COMBIN39)are used to describe the nonlinear behavior of semi-rigid connections.By comparing the hysteresis curve of steel frame of the four different connections,discuss the energy dissipation effect of the steel frame which is use semi-rigid connections,provides some references for the design of steel frame with semi-rigid connection. |
