| 摘 要： | 分别采用ANSYS有限元分析软件和Eurocode 3中的组件法对加入垫板的平齐式端板连接梁柱节点进行了模拟,并将模拟结果与试验结果进行了对比。结果表明：有限元分析所得的弯矩-相对转角曲线以及滞回曲线与试验结果基本吻合,节点的变形也与试验中观察到的变形一致,有限元分析可以很好地模拟此类节点的转动能力和刚度变化;采用组件法计算平齐式端板连接梁柱节点的刚度具有令人满意的精度;垫板的加入对节点整体性能没有太大的影响。

| Abstract: | The flush end-plate beam-to-column joints with inserted plate were modeled using finite element software ANSYS and component method provided in Eurocode 3. The modeled results were compared with experimental results. The results show that the finite element analysis and the experimental data give the similar moment-rotation curves, hysteretic curves and joint deformations; the rotation capacity and stiffness of this type of joint can be simulated well with the finite element method. The stiffness of the joints with satisfying accuracy can be obtained by using component method. The inserted plate does not influence the behavior of beam-to-column joints. |
