| 摘 要： | 采用有限元分析程序ANSYS,对18m跨门式刚架的稳定性进行了有限元分析,主要考虑几何大变形下,水平荷载和切线模量对刚架稳定性的影响。通过研究与分析,得到了以下结论：刚架承载力随着水平荷载的增大而逐渐减小,随着切线模量的增大而逐渐增大。

| Abstract: | This paper analyzes the stability of the portal frame with 18m span by using the finite program,considers the influences of horizontal load on the portal frame and the tangent module on the stability of frame portal under the large deformation,and obtains the following conclusion:the load-carrying capability of the portal frame decreases when the horizontal load increases,and increases as the tangent module increases. |

| Keywords: | portal frame horizontal load plasticity of material finite element analysis |
