摘要
木材在高温中的表现是当前木结构防火研究中的一个热点和难点,理解其炭化行为对木结构防火设计和防控至关重要。国外对木材炭化行为进行了全面系统的研究,而我国此类研究鲜少。笔者从现有炭化速率推荐值、炭化行为的影响因子、炭化模型的建立以及木材炭化微观构造这四个方面对国内外木材炭化行为研究进行梳理和总结,旨在为我国木材炭化行为系统研究和木结构防火设计规范制定提供参考和借鉴。
The performance of wood under high temperature has been a hot issue in the research on fire protection of timber structure, so it was very important for timber structure fire protection design and control to comprehend its charring behavior. A comprehensive research on wood carbonization behavior has been conducted in foreign countries while such studies were still rare in China. Therefore, the domestic and foreign researches of charring behavior were reviewed and summarized from four aspects, such as the recommended charring rates, influencing factors of charring behavior, establishment of carbonization model and wood carbonized microcosmic structure. The study will be aimed to provide reference for systematic research of the behavior of wood charring and the formulation of fire design specifications of timber structures.
