中文摘要	2008年初南方遭遇罕见降雪,连同2007年初的东北暴雪,均造成大范围地区的严重受灾,并涉及方方面面。其中,轻型房屋钢结构自身的超载能力差,遇到这种罕遇荷载后发生大量事故,有必要对事故的原因进行分析与反思。针对门式刚架轻钢工业厂房的事故进行较全面的分析,包括结构安全度、雪荷载的整体超载、建筑外形不当导致的局部积雪超载和清雪引发的次生灾害等内容,并通过分析,总结上述问题中包含的具体事故原因。最后在结构设计、建筑外形设计、规范和清雪措施等多方面反思,进而对当前轻型房屋钢结构设计提出相关建议。; In early 2008, Southern China encountered an unusual snowstorm, same as the early 2007′s Northeast snowstorm. They both caused a large disaster area, involving many aspects of society and the environment. Steel structures of light-weight buildings perform poorly at overload capacity, when they encountered such unusual snow loads, and caused a large number of accidents. Analysis and reflection on the accident causes is necessary. This paper conducts an overall analysis of light-weight steel industrial buildings with portal frames, including structure safety, integral overload of snow, local overload of snow due to improper architectural appearance and secondary disaster caused by unreasonable snow cleaning, etc. The paper also summarizes the concrete causes of the above problems. The paper reflects on aspects such as structure design, architectural appearance design, code and snow cleaning method, etc, and provides suggestions on design of steel structures of light-weight buildings.; “十一五”国家科技支撑计划课题(2006BAJ03A02-1)
