摘要
提出了一种在性能化防火设计中人员疏散问题安全性的评估方法 ,该方法是把火灾烟气运动规律、建筑物结构和人员疏散特点结合的研究成果 ,分别计算建筑物中不同单元内的火灾荷载阈值 ,在发生火灾时 ,烟气达到危险状态的时间和人员疏散所用的时间 ,比较这两个时间来确定建筑物防火设计是否达到性能化防火中人员安全疏散的要求。该方法从控制建筑物内火灾荷载的多少和建筑物的结构出发 ,在现行的计算软件的基础上 ,可用于实际的火灾安全工程设计和火灾安全咨询。
Based on movement of smoke, structure of building and needed time of evacuation, a performance-based fire safety design safety evaluation method for evacuation in building fires has been presented. By calculating the time of fire smoke arrive to risk situation and occupant evacuation time respectively, and then to compare these two kind of values to ensure the fireproofing of building reach to require of occupant evacuation in performance-based fire safety design. According to building structure and control fire load value in building, this method is run on fire models. Because of its simplicity and easy operation, this method can help fire safety design and fire safety consulting.
