| 摘 要： | 根据钢框架稳定设计中柱计算长度的概念，采用螺旋弹簧模拟梁柱连接半刚性，通过引入半刚性连接刚度修正系数，导出了有侧移半刚接钢框架柱计算长度系数的修正公式．在ANSYS模拟中考虑了半刚性节点非线性转动，对半刚接钢框架屈曲载荷进行了数值计算，并回归出半刚接框架柱计算长度系数的简化公式，以供工程设计参考．

| Abstract: | On the basis of the concept of effective length of columns in the stability design,a modified effective length factor formulas of semi-rigid steel frames are derived by joint relative rotation and the modified factor of the beam-to-column linear stiffness ratio under consideration.Buckling load of semi-rigid steel frame is simulated in ANSYS analysis and a simplified formula is made for effective length of semi-rigid steel frame.It can be used for engineering design. |
