摘　　要：将金属拱型波纹屋盖结构模拟成带肋的正交异性筒壳 ,运用由空间梁单元和板壳元组成的混合有限元程序对屋盖结构进行几何非线性分析 ,从而明确了不同的山墙构造对不同纵跨比屋盖结构承载力的影响 ,得到了一些有用的结论 。Arched corrugated metal roof is modeled as ribbed orthotropic shell,and analyzed with geometrically nonlinear finite element program composed of spatial beam element and shell element.The influence of different end wall constitutions on the load bearing capacity of the roofs with different length to span ratios is made clear,and some valuable conclusions are drawn from the study.

关 键 词：金属拱型波纹屋盖 山墙 纵跨比 等效正交异性 几何非线性 结构承载力
