| Abstract: | 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. |
