| 摘 要： | 应用ANSYS有限元程序,在均布荷载作用下,对不同高跨比的门式刚架进行了弹性几何非线性分析。研究表明,在均布荷载作用下,除了梁柱线刚度比,刚架高跨比及屋顶坡度对刚架的稳定性能影响很大。

| Abstract: | In order to discuss the in-plane stability of the steel portal frames with different ratio of depth to span which is subjected to roof uniform loading,the ANSYS finite element program is used to perform geometrically nonlinear analysis.It is indicated that apart from stiffness factor of beam to column,the ratio of depth to span and slop of roof greatly affect the stability performance of the portal frame under roof uniform loading. |

| Keywords: | ratio of depth to span portal frame in-plane stability instability mode effective length factor |
