随着我国社会经济的快速发展,很多大型工业建筑和超高层建筑也逐渐增多,这就对建筑物的建材提出了更高的要求。由于钢结构建筑和其他建筑相比,具有重量轻、强度高、抗震功能好的优势,而且施工时间上相对较短,材料可再利用和回收,因此相对而言综合效益较高,近年来在建筑行业得到了广泛的应用。但是由于钢结构本身的耐火性非常低,火灾情况下很容易引发严重的事故,给建筑物的安全造成了极大的威胁。为了提高钢结构的耐火性能,还需要对钢结构的耐火性进行分析,并采取一定的措施对钢结构进行防火保护。为此本文对钢结构的耐火性能做了简述,重点讲述了提升耐火性能的有效方法,以期提升建筑物的整体耐火安全性。
With the rapid socio-economic development in our country, many large-scale industrial buildings and super-tall buildings are also gradually increasing, which puts higher demands on building materials. Compared with other buildings, steel structures have the advantages of light weight, high strength and good anti-seismic function, and the construction time is relatively short, the materials can be reused and recycled, so the comprehensive benefits are relatively high. In recent years, The construction industry has been widely used. However, due to the very low fire resistance of the steel structure itself, fire accidents can easily lead to serious accidents, posing a great threat to the safety of buildings. In order to improve the fire resistance of steel structure, it is also necessary to analyze the fire resistance of the steel structure and to take certain measures to fire protection of the steel structure. In this paper, the fire resistance of steel structure is briefly described, highlighting the effective ways to improve the fire resistance, in order to enhance the overall fire safety of the building.
