木结构防火设计方法简介

Introduction to Fire Design Methods of Timber Structures

木材是唯一可再生的主要工业材料,对环境最为友好,是人类历史中的一种重要的建筑材料;但作为一种生物材料,木材具有易燃性,要确保木结构安全,就得充分重视木结构的防火设计。我国传统建筑主要是木结构建筑,其防火问题在我国很早就引起了重视,首先回顾了传统的防火设计方法;然后介绍了1h火灾防护方法,并详细分析了国内外不同木结构体系防火的设计、研究和思路等;其次简要介绍了木材的化学阻燃方法;最后总结木结构各种防火设计方法,提出存在的问题和未来研究的方向。

Wood is the only one industrial material that is renewable,most friendly to the environment,a kind of important building materials in human history.But as a kind of biological material,it＇s inflammable.To ensure the safety of timber structures,we must pay much attention to fire safety design.Wood construction was the mainstream of Chinese traditional buildings,whose fire problem has long been brought to the forefront.This paper at first reviews the traditional methods of fire design,then introducing one hour fire resistive method,analyzing the design,research and innovation of fire resistance of different wood structures at home and abroad.After that it briefly introduces fire retardant chemistry of wood,finally summarizing advantages,disadvantages and applicability of various methods mentioned in this article,putting forward the existing problems and future research.
