工业仓库的消防安全性能设计

Application of Performance Design Method of Fire Safety in an Industrial Warehouse

以工业仓库为例 ,采取消防安全性能设计新理念 ,在保证人员人身安全的前提下 ,探讨排烟系统性能以及人员疏散问题 ,利用简单分析与计算机模拟技术相结合的方法定量分析安全疏散时间等相关特性 .同时 ,对火源设定、排烟条件以及疏散出口等不同条件下的火灾场景进行了研究 ,并对部分场景进行了三维CFD计算 .研究表明 ,作为现有处方式法规的一种变通 。

The new performance-based code fire safety design method is applied in this paper,in regard to the protection of life safety of the occupants.The evaluation of the performance of a smoke venting system and the exit distribution is given in an industrial warehouse.Quantitative analyses of the available safe egress time and the required safe egress time are carried out by using combined simple calculation and computer modelling technique including zone model and 3D CFD model.This study includes sensitivity analysis to investigate multiple fire scenarios involving variations in design fires,ventilation conditions and numbers of exits.
