摘要

时间等效法是确定建筑物防火等级的一种方法。其中一个需要的输入参数是火灾负荷能量密度,在确定性设计中,这是一个固定的值。本文说明了使用一个简单的蒙特卡罗工具,该工具将汽车能量含量的统计变化作为车辆大小的函数,以确定基于风险的停车场设计计算方法的概率逃离值。本文简要讨论了在文献中可以找到的停车场建筑的逃离值,蒙特卡罗工具的结果表明,260 MJ/m2可以作为合适的设计值,而不是使用概率方法。

Fire load energy densities for risk-based design of car parking buildings

The time-equivalence method is one way to determine the appropriate fire severity in buildings. One of the input parameters required is the fire load energy density (FLED) and in a deterministic design this is taken to be a fixed value. This paper illustrates the use of a simple Monte Carlo tool that accounts for statistical variations in car energy content as a function of vehicle size to determine probabilistic FLED values for a risk-based calculation approach to the design of car parking buildings. The paper briefly discusses FLED values for car parking buildings that can be found in the literature and results from the Monte Carlo tool suggest that 260 MJ/m2 could be used as an appropriate design value in lieu of using a probabilistic approach.
