摘要:
通过总结各国在全盛期室内火灾升温的参数化模型研究领域的成果和统计国外火灾荷载调查数据,分析了模型输入参数的随机性,建立了火灾荷载密度、开口因子和房间壁面热惰性的概率分布模型,并给出了不同用途房间的火灾荷载密度均值和变异系数、开口因子模型参数的概率密度函数及不同房间壁面热惰性的范围。结果表明,火灾荷载密度服从正态分布,开口因子模型中的参数服从对数正态分布,而房间壁面的热惰性可认为是均匀分布的随机变量。
Abstract:
Authors analyzed the randomness of the parameters by reviewing the research field of parametric models of fully-developed compartment fire and conducting statistical calculation of data from fire load surveys of some foreign countries. The probability distribution models of fire load density, ventilation factor and thermal absorptivity of wall were established. The mean values and coefficients of variation of fire load density of different occupancies, as well as the probability density function of the parameter of the ventilation factor model and the ranges of thermal absorptivities of different types of walls were presented.It is shown that fire load density follows normal distribution and the parameter of the ventilation factor model follows log normal distribution. Thermal absorptivity of wall can be modeled as a variable that follows uniform distribution.
