建筑火灾烟气危害评价模型及应用

Building fire smoke hazards evaluating model and its application

在FED理论基础上,参考SII烟气伤害模型提出一个考虑烟气温度、能见度和毒性综合作用的人员伤害模型,并在该模型基础上开发基于GIS的火灾烟气危害评价系统。该系统可以确定建筑室内火灾中烟气综合危害分布和毒性分布随时间变化的情况,并得出性能化防火设计重要参数之一ASET,为火灾人员疏散提供参考依据。

Based on the theory of FED, and taking SII smoke damage model as reference, a personal injury model considering the combined action of smoke temperature, visibility and toxici- ty is proposed and a system based on the model and GIS is developed. The system can evaluate the integrated hazards and taxicity changing over time, and get the important parameter of perform-based fire design, available safety egress time, to provide references for evacuation in fire.
