摘要
火灾高温对结构材性有显著影响,因此火灾极易造成结构损伤、破坏甚至倒塌。随着建筑事业的发展和建设水平的提高,如何合理进行结构的抗火设计正越来越受到学术界和工程界的关注。本文简要回顾了结构抗火研究历史,论述了近年来结构抗火研究的主要进展,指出了结构抗火研究尚存在的问题,对结构抗火研究趋势进行了展望,并提出了目前抗火研究尚需解决的关键科学问题。
The properties of strtuctural material are greatly varied in high temperature caused by fire,which lead the damage or even collapse of structures. The fire-resistance of structures is paid more and more attention by academics and engi neers. The history of the research on fire resistance of structures is briefly reviewed and the main progress in the re- search on the fire-resistance of structures in recent years is presented. The remained problems for the fire-resistant design of structures is pointed out and the key problems needed further research on fire resistance of structures are proposed.
