摘　　要：随着现代木结构逐渐成为新的热点,木结构建筑的防火问题变得尤为重要。基于国内外现有研究成果,对木材受火时的微观结构变化、炭化速度进行总结;把国内外学者对木构件、整体木结构进行的有限元分析及试验情况做了归纳;对国内外有关技术标准中关于木结构建筑防火条文进行分析,并分别针对轻、重型木结构的防火设计予以讨论;对目前木结构建筑施工时防火处理做法进行探讨;根据我国木结构建筑防火现状,对今后的防火研究重点做出展望。With modern wood structure gradually being a new hot spot, fire safety problem of wood construction is particularly important. Based on existing research results both at home and abroad, the change of micro-structure of wood and its charring rate were summarized. The research of the finite element analysis and experiment of timber component, wood joint, and wood structure were also summarized. The domestic and international specifications of wood structure were analyzed, the design norm of light wood frame construction and heavy timber construction was discussed. The fireproof treatment in construction state was explored. Contraposing the status quo of Chinese wood structure fire resistance, it was raised further research priorities and prospects for the future development were made.
