| 摘 要： | 目的研究利用柱腹板屈曲后强度轻钢框架加强型中节点在地震荷载作用下的抗震性能,为轻钢结构抗震设计提供参考.方法对两组轻钢框架中节点进行低周往复循环载荷下（拟静力）的抗震性能试验研究,采用ABAQUS非线性有限元程序进行仿真,与试验结果进行对比,以验证有限元模拟的正确性.结果采用增加横向及纵向加劲肋的方式进行加强的中节点具有较强的吸能耗能能力和变形能力.所建立的ABAQYS有限元模拟程序能对此试验过程进行有效的全过程模拟.结论两类不同加强方式的轻钢框架中节点具有良好的抗震性能,有限元模拟分析具有良好的仿真性及有效性.

| Abstract: | To study the anti-seismic property of light steel frame reinforce middle joints when the column w eb buckling,and provide a reference for seismic design of light steel structure. Conduct tw o groups of experiment on light steel frame joints’ seismic performance under low cycle loading,and using nonlinear finite element program ABAQUS simulates the joints’ performance,and compares the result w ith the test result, and lays a foundation for future numerical simulation. The joint strengthened by increasing horizontal and vertical stiffener ABAQUS finite element simulation is effective in the w hole process of simulation test process. Tw o types of strengthened joints on the light steel frame has good seismic performance,and simulation and finite element simulation analysis has good effectiveness. |
