| 摘 要： | 利用欧洲规范3与欧洲规范4介绍的组件法思想,针对已有的端板连接组合节点初始转动刚度分析方法的不足,提出了端板连接组合节点负弯矩作用下节点初始转动刚度的详细计算步骤;考虑板内纵筋与剪力栓钉竖向位置的不同及桩腹板加劲肋的影响,给出了初始转动刚度组件法分析模型.将分析结果与试验结果进行了比较验证,结果表明该分析方法精度较好,能够用于工程设计中对该类节点初始转动刚度的预测.

| Abstract: | Using the component method introduced in Eurocode3 and Eurocode4, and aiming at the existing methodical shortage of end-plate beam-column composite joint initial rotational stiffness analysis, we proposed a detailed calculating procedure for the end-plate beam-column composite joint under hogging moment. Considering the influence of different location of longitudinal reinforcement and shear stud and that of stiffness of column web, a component model for initial rotational stiffness analysis was presented. The analytic result was compared with that of experiment. The result indicates that this method is of satisfactory accuracy , and it can be used to predict the initial rotational stiffness of this type of joints in engineering design. |
