| 摘 要： | 用有限元方法对双层单跨支撑框架进行弹性整体稳定分析，得到了从无支撑框架过渡到完全支撑框架时相应的柱计算长度系数，非完全支撑框 完全支撑框架间存在一个门槛刚度，该刚度值可作为框架有侧移和无侧移的区分标准。

| Abstract: | The elastic stability of steel frame with bending-type system is studied in this paper.By use of the finite element method,the effective length factor of columns in unbraced frames,braced frames and partially-braced frames are obtained.The threshold stiffness of the bracing may be used as a criteria to judge the sway and non-sway frames in stability calculation. |
