| 摘 要： | 基于性能化防火设计的研究思路，以A教学楼为例，讨论了教学楼现有疏散设施是否符合火灾场景下人员疏散要求。运用火灾模拟软件PyroSim建立火灾模型，得出影响疏散的温度、能见度、烟气的运动规律，选取最不利因素，确定可用安全疏散时间（ASET）。通过人员疏散软件Pathfinder模拟人员疏散路径，得出所需安全疏散时间（RSET）。研究结果表明，PyroSim与Pathfinder能有效的模拟火灾下人员疏散规律，A教学楼不能满足疏散要求，并提出改进方案以确保疏散安全。

| Abstract: | The fireproof condition of the existing evacuation facilities of a school building at certain university in Fuzhou under fire scenario was discussed in the perspective of performance based fire proof design. Fire dynamic simulation software PyroSim was used to formulate an evacuation model. The effects of temperature, visibility and the movement of fume (flue gas) on the evacuation were obtained. The most unfavourable factor was selected to determine available safe evacuation time (ASET). The evacuation path of the personnel was simulated via personnel evacuation software Pathfinder, and the required safe evacuation time (RSET) was determined. The results show that PyroSim and Pathfinder can effectively simulate personnel evacuation under fire scenario. The improvement scheme for the evacuation of the school building was proposed to ensure safe evacuation. |
