摘　　要：钢结构作为一种建筑材料,由于它的塑性及韧性较好,正逐步取代其他建筑材料,成为现代建筑材料的主体。但钢结构耐火性能差,一直让人担忧其危及新造建筑的安全。为了认清钢结构构件在经历火灾后的受损情况,以及受损后的钢构能否继续安全使用,必须进行科学、准确、合理的检测和鉴定。该文结合实际工程案例,对火灾后的钢结构厂房现场状况进行描述,并详细介绍火灾后钢结构建筑安全性鉴定的内容,对火灾后钢结构构件受损情况进行深入分析,为类似建筑工程安全使用钢结构材料提供参考。As a building material,the steel structure is gradually replacing other building materials to become the main body of modern building materials due to its remarkable plasticity and toughness.However,the poor fire resistance of the steel structures has been a concern of people about the safety of new buildings.In order to identify the damage of the steel structure components after fire,and whether the damaged steel structure can continue to be used safely,scientific,accurate and reasonable inspection and identification must be carried out.Based on an engineering case,this paper described the on-site conditions of the steel structure factory building after fire,laid out the contents of the safety appraisal of the steel structure building after fire,and made an in-depth analysis of the damage of steel structure components after fire,hoping to provide a reference for the safe use of steel structure materials in similar construction projects.
