摘　　要：在对某单层工业厂房倒塌现场调查的基础上,对厂房倒塌特征进行了描述,采用有限元方法对钢屋架结构在恒载和屋面活载(或雪荷载)作用下的内力及应进一步力进行了计算,分析了厂房倒塌的原因,分析结果与现场调查情况基本一致,在雪灾抗倒塌分析的基础上,取得了一些有意义的结论和启示。Based on the spot investigation of a certain one-story steel industrial factory building collapsed during snow disaster,the damage state of the structural members in the building was described in detail.The internal forces and stresses of the steel roof truss under dead loads and live loads were calculated by means of finite element method,in order to clarify the collapse causes of the steel industrial factory building.The numeral simulation analytic solution is in agreement with the result of spot investigation.Some meaningful conclusions and inspiration are obtained from the further analysis of anti-collapse of building against snow disaster.
