| 中文摘要: |
| 以高层建筑为研究对象，应用FDS软件对高层建筑火灾燃烧规律进行数值模拟计算。得到了高层建筑火灾时的烟气运动、着火点附近区域温度变化、CO2浓度变化等火灾参数变化规律的数值模拟计算结果。结果显示：在高层建筑火灾发生300s左右时，火灾开始进入轰燃阶段，火场烟气迅速蔓延，火场温度迅速上升到600℃。数值模拟计算结果为高层建筑性能化防火设计及人员紧急疏散提供一定的理论依据。 |
| 英文摘要: |
| FDS software is operated to simulate the combustion of high-rise building fire. The numerical simulation calculation results of the fire parameters change are obtained, including smoke movement, temperature variation and CO2 concentration variation, etc. Results show that when fire in high-rise building occurs about 300s it begins to enter the flashover stage, smoke spreading rapidly and fire temperature rising to 600C quickly. The numerical simulation calculation results can provide theoretical basis for performance-based fire design and emergency evacuation of high-rise building. |
