摘要
通过对波纹拱壳屋顶结构存在问题的讨论 ,介绍了一种新型薄壁拱壳结构 ,即无波纹拱壳屋顶。并分析了适合于这种结构的几何非线性有限元理论。最后 ,通过算例对无波纹拱壳结构的极限承载力与波纹拱壳结构进行了比较 。
The problems lied in corrugated arch\|shell structure is discussed and a new type of thin\|wall steel structure\_\_non\|corrugated arch\|shell roof structure is introduced.Theoretical analysis of geometric nonlinear finite element is done.At last,a conclusion that the stability carrying capacity of the non\|corrugated arch\|shell structure is higher than that of the corrugated arch\|shell structure is made after calculation.
