| 摘 要： | 柱计算长度法是钢框架稳定设计的常用方法,顶底角钢连接梁柱节点是一种典型的半刚性梁柱节点。采用抗弯弹簧模拟梁柱节点连接的半刚性,得到顶底角钢半刚接形式对钢框架柱计算长度系数的影响。运用有限元分析方法对其进行对比分析。

| Abstract: | Effective length method is a commonly used method in steel frames stability design.Top and bottom steel angle node is a typical semi-rigid node.The top and boottom steel angle semi-rigid connected steel frames are separated by the joint relative rotation under consideration.By adopting the modified stiffness factor,The semi-rigid connection is stimulated by a rotational spring.Which are analyzed by FE method. |
