展览建筑火灾场景设置方法分析

摘要

结合应用实例,探讨了展览建筑火灾场景设置的程序和思路.展览建筑性能化防火设计中火灾场景的设置应综合分析其火灾危险性及火灾荷载,将火源位置设置在最不利点,重点关注自动喷水灭火系统和防排烟系统有效性,分析火灾增长速率及火灾是否蔓延,结合火灾扑救确定最大热释放速率.%The procedure and thinking of fire scenario about exhibition building was discussed with the example. The fire risk and fire load should be considered in fire scenario setting of performance-based fire protection design of exhibition building. The fire point should be set at the most unfavorable location and the effectiveness of auto-sprinkler system and smoke control system should be focused on. The fire growth rate and the fire spread or not should be analysis. The maximum heat release rate should be defined consider of fire fighting.
