摘　　要：拱形波纹钢屋盖结构因造价低廉、施工速度快等优点而常被应用于仓储类简易结构。由于研究较少,相关技术规程2005年才颁布实施,在此之前由于设计理论不统一等原因各地工程事故频频出现。针对一典型屋盖倒塌工程事故,采用不同计算方法进行分析,同时分析风荷载取值、风动力效应等因素对屋盖倒塌的影响。结果表明,风荷载和风动力作用是造成倒塌的主要原因,设计时应根据结构所处位置综合考虑荷载取值,规程所采用的计算方法具有一定的安全度,可以用于此类屋盖结构的设计。　Arched corrugated steel roof is often used for storage buildings because of its low cost and shorter construction time.The related technical regulations was carried out until 2005 because of the limited research,and collapse accidents were occurred frequently in China because the unified methods were not existing before this time.A typical accident was analyzed based on different calculate methods,wind load and wind dynamical action were also discussed.The collapse was mainly because of the wind load and wind dynamical action.The wind load value should be considered according to the structure location.The methods which the regulations adopted are safe,it can be used in practice.
