| 摘 要： | 为研究改变双向弯矩的大小和方向对钢框架刚性节点的抗震性能,采用ANSYS对4个刚性节点的钢框架在双向弯矩作用下进行三维有限元模拟,并且全面、系统地分析了刚性连接钢框架节点在受双向弯矩作用的延性、耗能及破坏形态。研究发现,改变弯矩的大小对刚性连接节点的延性产生较大程度的影响,尤其是弱轴施加弯矩变号时,结构的承载力、耗能性能都随之上升。

| Abstract: | Based on test of 4 joints of steel frames under double-direction moment loading,the anti-seismic behavior of joints of steel structure was studied by changing direction and sizes.3D finite element method is used.Results shows that changing the directions and sizes could affect the ductility of rigid connections in steel frames,especially the ductility and energy dissipation were increased. |
