Arch shape corrugated shell roof is a new light steel structure. It is widely used due to its low costs, and short construction period. However, since 1996, a number of this kind of roof has been collapsed when hit by strong wind and heavy snow. These accidents have attracted great attention by the construction industry. In this article, the causes of these accidents, such as the design theory, shape forming technology, construction technology and materials used are explored. Factors impacting the safety of...

Arch shape corrugated shell roof is a new light steel structure. It is widely used due to its low costs, and short construction period. However, since 1996, a number of this kind of roof has been collapsed when hit by strong wind and heavy snow. These accidents have attracted great attention by the construction industry. In this article, the causes of these accidents, such as the design theory, shape forming technology, construction technology and materials used are explored. Factors impacting the safety of this kind of roof were analyzed, and their improved safety measures to prevent collapse accidents are suggested.

波纹拱壳屋顶是一种新型的大跨轻钢结构。由于其造价低、施工期短 ,在国内已得到大规模的应用。1996年起 ,我国有几十个大跨波纹拱壳屋顶由于大风或大雪而相继发生坍塌事故 ,这类伤亡事故引起了业界的高度重视。笔者从波纹拱壳屋顶的设计理论、成型工艺、施工工艺、材质等几个方面探讨了波纹拱壳屋顶发生坍塌的原因 ,分析了影响波纹拱壳屋顶安全性能的几个主要因素 ,还提出了防止该结构倒塌的安全改进措施

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.

To simulate the actual wave shape of metal corrugated arch shell roof structure by subdividing the grids of finite element model is an effective analytical method,but that causes the grids to be very dense and the finite element model also to be more complicated A program is compiled to realize the automatic division of the finite element grids of metal corrugated arch shell structure using the theory of automatically dividing the finite...

To simulate the actual wave shape of metal corrugated arch shell roof structure by subdividing the grids of finite element model is an effective analytical method,but that causes the grids to be very dense and the finite element model also to be more complicated A program is compiled to realize the automatic division of the finite element grids of metal corrugated arch shell structure using the theory of automatically dividing the finite element grids By using the program,the time that computer takes to establish model can be saved,and the false operation due to manually establishing the finite element model and dividing the grids can be avoided

用细化有限元模型网格的方法来模拟金属波纹拱壳屋顶结构实际的波纹形状是一种有效的分析方法 ,但却使得网格非常密集 ,有限元模型比较复杂。应用有限元网格自动剖分理论 ,采用平面超单元变换剖分法 ,编写程序实现了金属波纹拱壳结构有限元模型网格的自动剖分 ,大大节省了计算机建模时间 ,并避免了在手动建模及划分有限元网格时所出现的误操作
