介绍兰州中川机场新航站楼应用性能化防火设计,解决防火分区面积过大、安全疏散过长等问题。设计10个火灾场景,用EVACNET4软件模拟航站楼各部分人员疏散时间;FDS模拟烟气运动,得到可用疏散时间。经模拟分析,得出各场景下人员均能安全疏散。另外设计2个火灾场景,模拟顶棚及幕墙钢结构的防火安全性。结果显示,在现有的防火安全条件下,火灾不会影响钢结构的安全。建议部分钢结构使用薄型防火涂料进行防火保护。
Introducing Lanzhou Zhongchuan Airport new terminal application of fire performance design to solve the fire district is too large, safe evacuation is too long and so on. Designing 10 fire scenes, using EVACNET4 software to simulate the evacuation time of all parts of the terminal building; FDS simulation of flue gas movement, available evacuation time. After the simulation analysis, it can be concluded that all the personnel can evacuate safely. In addition, two fire scenes were designed to simulate the fire safety of ceiling and curtain wall steel structures. The results show that under the existing fire safety conditions, the fire will not affect the safety of the steel structure. Proposed part of the steel structure using thin fire retardant coating for fire protection.
