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.
