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。
On the basis of the investigation on the collapse of a single-storey industrial building, the characteristics of the plant collapse are described. The internal force of the steel truss structure under the action of dead load and roof live load (or snow load) and the further force The reasons for the collapse of the factory building are analyzed. The analysis results are basically in line with the field investigation. Based on the analysis of snowstorm collapse resistance, some meaningful conclusions and enlightenments have been obtained.
