摘要:

文章利用火灾风险理论,充分考虑消防重点部位及可燃物存放当量的量化评估因素,包括火灾危险源的辨识、火灾荷载密度、等效燃料面积、通风因子、燃烧类型指数、热释放率、火灾持续时间、火灾温度,温度对建筑材料力学性能的影响等,对钢及混凝土材料受热后力学性能损失和能量释放概率进行分级,引入严重因子和概率因子,提出通过计算火灾风险因子(严重因子与概率因子的乘积)来作为消防重点部位判定依据,同时为可燃物存放当量的量化评估提供了方法。

Abstract:

The fire hazards are calculated and analyzed from many aspects based on the theory of fire risk. Taking fully into account the quantitative assessment factors of the key parts of fire safety and the storage equivalent of combustible materials, fire load density, equivalent fuel area, ventilation factor, combustion type index, heat release rate, fire duration fire temperature, temperature effect on mechanical properties of building materials the mechanical performance loss and energy release probability of steel and concrete materials after heating are classified, and the severity factor and probability factor are introduced. By calculating the product of fire risk factors as the basis for judging the key parts of fire protection, this paper puts forward a specific and feasible management strategy for the management of key parts of fire safety.
