Abstract

Steel structures themselves have the characteristics of light weight, high strength, easy construction, and recycling, and are widely used in the construction field. However, in the context of the rapid development of the construction industry, there are more and more safety hazards in buildings, and steel structure fire protection design is particularly important. Fire, as an important factor affecting the safety of buildings and people's lives and property, needs to be taken seriously in the design process of building steel structures. Steel itself does not burn, but as a metal, it has good thermal conductivity. In the event of a fire, it only takes more than ten minutes to reach the critical temperature of the steel itself. The steel's load-bearing capacity sharply weakens, causing building collapse, causing casualties and economic losses. Therefore, it is necessary to carry out fire prevention treatment for steel structure buildings, and currently there are many fire prevention methods applicable to steel structure buildings. How to reasonably select the fire prevention methods suitable for prefabricated steel structure buildings is also a problem faced by designers. Based on this, this article analyzes the hazards of steel structure buildings themselves, understands the problems in fire protection of steel structure buildings, and proposes countermeasures to strengthen fire protection of steel structure buildings, aiming to improve the fire performance of steel structure buildings.
钢结构防火设计研究
钢结构本身具有重量轻、强度高、施工方便、可回收利用等特点,在建筑领域得到了广泛的应用。然而,在建筑业快速发展的背景下,建筑的安全隐患越来越多,钢结构防火设计就显得尤为重要。火灾作为影响建筑物安全和人民生命财产安全的重要因素,在建筑钢结构设计过程中需要引起重视。钢本身不燃烧,但作为一种金属,它具有良好的导热性。如果发生火灾,只需要十多分钟就能达到钢铁本身的临界温度。钢材的承载能力急剧减弱,造成建筑物倒塌,造成人员伤亡和经济损失。因此,有必要对钢结构建筑进行防火处理,目前适用于钢结构建筑的防火方法有很多。如何合理选择适合装配式钢结构建筑的防火方式也是设计者面临的问题。基于此,本文分析了钢结构建筑本身存在的危害,了解钢结构建筑在防火方面存在的问题,并提出了加强钢结构建筑防火的对策,旨在提高钢结构建筑的防火性能。
