摘　　要：对某门式刚架轻钢结构厂房发生倒塌事故进行分析与计算复核的结果表明:在施工过程中,如未采取有效措施使其形成稳定的空间结构体系,极易受到极端天气下风荷载的影响发生倒塌倾覆破坏。门式刚架轻钢结构厂房的现场施工,应根据国家相关规范规程制定施工方案,并严格遵守施工方案进行施工,防止类似事故再次发生。Through the analysis and calculation of the collapse accident of a gantry steel structure workshop. The results show that in the process of construction, if effective measures are not taken to form a stable spatial structure system, it is extremely easy to be affected by the wind load in extreme weather. According to the relevant national regulations, the construction plan should be formulated according to the relevant national regulations. And strictly abide by the construction plan to prevent similar accidents from happening again.
