基于PyroSim和Pathfinder的商业建筑共用楼梯间安全疏散研究

Research on Shared Stairwell Evacuation in Commercial Buildings Based on PyroSim and Pathfinder

随着商业建筑的功能复合与大规模化发展,其安全疏散问题变得更加复杂,若没有合理的疏散设计,发生火灾时会造成严重后果。因此,商业建筑人员疏散问题成为当前亟待解决的重要课题。利用PyroSim和Pathfinder定量分析商业建筑可用安全疏散时间和所需安全疏散时间,得出不同火灾场景下人员疏散安全性。进一步对特定场景下共用楼梯间的安全疏散进行多工况模拟,提出增加其疏散宽度可满足特定火灾场景下的人员安全疏散要求。

With the functional and large-scale development of commercial buildings,the issue of safety evacuation becomes more complicated.Without proper evacuation plan,serious consequences can occur in the event of a fire.Therefore,the personnel evacuation of commercial buildings has become an important issue that needs to be addressed urgently.PyroSim and Pathfinder are used in the study to quantitatively analyze the available safe evacua⁃tion time and required safe evacuation time in commercial buildings,and determine the safety of personnel evacua⁃tion in different fire scenarios.Based on the multi-condition simulation of the shared stairwell evacuation in specific scenarios,this paper proposes increasing the evacuation width to meet the requirements for safe personnel evacuation in specific fire scenarios.
