In order to effectively reduce the incidence of sec-ondary fire losses, it is very meaningful making the scientific and reasonable safety appraisal of building structure after fire. Based on the above background, this paper deeply discusses the safety appraisal of building structure after fire from two aspects of theory and practice, which provides reference for si-milar research.%为了有效降低火灾二次损失的发生率,在火灾发生后对建筑物结构进行科学、合理的安全鉴定显得十分有意义。基于上述背景,本文从理论和实践两方面对火灾后建筑结构的安全鉴定问题进行了深入探讨,以期为同类课题的研究提供些许借鉴。
