创意概念型博览会展建筑消防性能化设计

Performance-based fire protection design of the creative conceptual exhibition architecture

结合某创意概念型博览会展建筑工程,针对其防火分区面积大、疏散距离长的问题进行性能化防火设计。设计7个场景,以FDS模拟烟气流动,使用EVACNET4模拟人员疏散情况。就此类建筑性能化设计中若干关键问题进行探讨。性能化设计的防火分区应与按规范要求设计的防火分区在安全性上等价或相似。应增强防排烟以弥补疏散距离长的缺陷。应考虑增配消防排烟车以增强应急救援能力。

The fire protection design of one creative conceptual exhibition architecture was done in performance-based way since the fire compartment is too big and the evacuation distance is too long.The smoke movement was simulated by FDS and the evacuation was simulated by EVACNET4 with 7 scenarios.The problems in performance-based design for this kind of building were discussed.The fire compartment designed in performance-based way should be as safety as the fire compartment designed by the Code.The smoke control should be enhanced to make up the defect of long evacuation distance.The emergency rescue should be enhanced by equipped with smoke exhaust vehicle.
