【摘要】 村镇建筑一般存在防火间距小、耐火等级低等问题，目前越来越多的村镇自建住宅被改为民宿等对外经营场所，功能改变之后，带来了疏散相对困难、火灾荷载增加等问题，导致其火灾风险进一步变大。将特殊防火设计方法应用于村镇建筑，以某典型村镇民宿建筑为例进行特殊防火设计，采用理论计算和数值模拟方式进行了人员疏散安全性分析、火灾蔓延安全性分析和结构安全性分析，给出了增设火灾自动报警装置、设置自闭门、安装甲级防火窗、增设不燃吊顶等解决策略，降低了建筑火灾风险，提高了消防安全性，为特殊防火设计方法在村镇建筑中的应用提供参考。更多还原

【Abstract】 Most rural buildings have smaller fire separation distance and lower fire-resistant levels. Now more and more rural residence is changed to a place of business, such as homestay inn. When the function is changed, the fire risk will increase because of evacuation difficulty and higher fire load. This paper applies performance-based fire design method to rural buildings.Performance-based fire design of a typical rural homestay inn was carried out. Uses theoretical calculation and numerical simulation methods, the safety of evacuation, fire spread and structure were analyzed. The strategy of adding automatic fire alarm device, setting self closing door, installing insulated fire window,adding noncombustible ceiling etc. were suggested. The strategy can decrease fire risk, increase fire safety, and provide a guide for the application of performance-based fire design in rural buildings.更多还原
