基于FDS和STEPS的大型商业综合体IMAX影厅火灾模拟与安全疏散研究

Study on Fire Design of an IMAX Theatre Based on FDS and STEPS Software

针对IMAX影厅面积普遍超过规范要求、火灾危险性大和人员疏散困难等因素,选取大型商业综合体的IMAX影厅为研究对象,在影厅及附近公共走道部分设计为独立防火分区,影厅内喷淋有效、排烟有效的条件下,采用FDS和STEPS软件进行厅内火灾模拟和人员疏散模拟.结果表明,影厅内烟气不会蔓延至走道等公共区域,环境未达到人员耐受极限,人员能安全疏散至公共区域,安全余量时间较大有利于消防队员的扑救和财产转移.

The IMAX theater of large commercial complex was choosed as the object of study.The public walkway part of the cinema and the nearby area is designed as an independent fire prevention zone.FDS and STEPS software were used to simulate the hall fire and personnel evacuation.The results showed that the flue gas will not spread to the aisle and other public areas in the theater,environmental personnel tolerance limit has not been achieved,people can safely evacuated from the public areas.The time of safe margin is larger,which is beneficial for fire fighting and properties transfer.
