摘　　要：通过对国内外钢结构抗火研究的现状分析,概括了国内外学者采用试验、有限元计算和弹塑性计算等主要方法对在火灾下钢结构的材料特性、整体性能和单件性能等领域的研究现状.分析钢结构抗火研究尚存在的问题,指出更精细模型的理论计算和实际火灾下的抗火风险评估是今后钢结构抗火研究主要发展方向.We have given an overview of its recent developments. The steel structure＇s material characteristics, whole performance and single - piece performance in case of fire have been studied. The main methods adopted by scholars at home and abroad are experiments, finite element calculation and elastoplastic calculation. The analysis concludes that the fire resistance of steel structure needs further research. The future study targets at establishing the theoretical calculation of a finer model and risk assessment of fire resistance.
