摘要
以某城市文化中心大剧院为例分析此类建筑的火灾危险性。针对该场所由于使用功能的限制,防火分区超过国家现行规范的情况,利用FDS软件设置6个火灾场景,设定不同的火灾增长系数和最大热释放速率,针对自动喷水灭火系统和排烟系统有效与失效的情况模拟烟气运动及人员疏散,对人员疏散的安全性进行评估。模拟结果显示,在满足一定条件时,大剧院内人员可以安全疏散。根据模拟结果提出增强消防安全性的措施。
The building fire hazard of grand theatre was dis cussed with the case of a cultural center grand theatre. Due to restrictions on the use funetion and fire compartment is greater than then current national specifications, six fire scenarios with different fire growth coefficient and maximum heat release rate were set to simulate flue gas movement and evacuation, and as- sess the safety of evacuation with the consideration of sprinkler system and exhaust system. The simulation results showed that, under certain conditions, people in theatre could evacuate safely. Severai measures to enhance the fire safety were pro- posed according to the simulation results.
