摘　　要：钢结构自身重量轻、强度高,在工程建设中得到广泛应用。但因其耐高温性能差,对钢结构建筑的安全性有较大影响,限制了钢结构的应用。基于传统防火方法之一的截流法设计原理,针对国内外相应耐火钢种的研究、应用情况进行简要回顾,着重介绍了耐火钢的性能参数、强化机理、生产工艺的研究现状及其抗震和焊接性能特点,对国内耐火钢的研究开发和推广应用具有较高参考价值。Featuring light weight and higher strength,the steel structure is widely applied in engineering construction.However,the poor high-temperature resistance has large influence on the safety of steel structural building,which restricts the application of steel structure.Based on the design principle of interception method of the traditional fire proof methods,the research and application of corresponding fire proof steel grades of both home and abroad are briefly reviewed,the current researches on properties parameters,strengthening mechanism production process and features of seismic resistance and weldability for fire proof steel are introduced and highlighted,which is of high reference value for the research,development and application promotion of fire proof steel.
