建筑基本空间火灾特性研究
|
摘要
根据建筑设计原理选取住宅建筑基本空间作为研究对象,在相同的火灾场景下使用同一标准火源对各空间进行火灾模拟,得到各空间达到火灾危险状态的时间作为其火灾特性指标。使用SPSS软件分析得到建筑空间要素(净面积、净高和通风因子)与火灾特性指标的定量关系,作为进一步深入研究复杂建筑空间火灾特性的依据和出发点。
The single-function space of residential building was selected as the research object.In the same fire scene,standard fire source was used to simulate the fire process in the single-function space.The time when space reached fire danger state was obtained as the fire characteristic index of space.SPSS was used to analyze the simulation data.The quantitative relationship between space factors including net area,net height and ventilation factor and fire characteristic index was obtained as a basis for the further study of fire characteristics of complex spaces.
