摘要
在分析大型会展中心主会议厅防火分区、防火分隔与安全疏散设计的基础之上,基于其消防性能化防火设计目标、火灾增长速率分析和性能化防火设计的条件,采用FDS模拟对大型会展中心主会议厅发生火灾时的温度、烟气蔓延特性进行模拟分析,模拟结果表明:在各消防设施有效动作的情况下,各设定火灾场景的人员可用疏散时间不小于1 200 s,大于720 s(12 min).在自动喷水灭火系统或排烟系统失效的情况下,人员可用疏散时间亦不低于1 076 s,大于720 s(12 min).在自动灭火系统和机械排烟系统均有效或者失效时,烟气均不会蔓延出会议厅而对其它区域的人员疏散造成影响.
Abstract
Based on the analysis of the fire partition,fire separation,and safe evacuation design of the main conference hall of a large exhibition center,FDS simulation was used to analyze the temperature and smoke spread characteristics of a fire in the main conference hall of a large exhibition center.The simula-tion results show that,under the effective operation of various fire protection facilities,the evacuation time for personnel in each set fire scenario shall not be less than 1 200 s and shall not exceed 720 s(12 min).In the event of failure of the automatic sprinkler or smoke exhaust system,the available evacuation time for personnel shall not be less than 1 076 s and shall not exceed 720 s(12 min).When both the automat-ic fire extinguishing system and the mechanical smoke exhaust system are effective or fail,the smoke will not spread out of the conference hall and affect the evacuation of personnel in other areas.
