基于MassMotion及PyroSim的高层宿舍火灾模拟研究

High-rise dormitory simulation based on MassMotion and PyroSim

使用PyroSim软件对某高校高层宿舍楼火灾进行模拟,通过烟气层高度、温度等火场数据的变化得出允许疏散时间ASET。使用MassMotion对宿舍楼内人员疏散进行模拟,得出需要疏散时间RSET,并提出增设疏散出口的改进意见,将模拟数据与经验公式计算的疏散时间相对比,分析导致造成结果差异主要因素。将ASET与RSET进行对比,判断该建筑的火灾危险性,并提出安全疏散措施及相关建议。

PyroSim was used to simulate a high-rise dormitory and the ASET was obtained through the fire field data such as smoke layer height,temperature and so on.MassMotion was used to simulate the evacuation and to obtain the RSET.The suggestion as improving an exit was put forward.The simulation data was compared with the evacuation time calculated by the empirical formula.The main factors which caused the difference in these results were analyzed.ASET was compared with RSET in order to determine the fire hazard of the building.Safety evacuation measures and related recommendations were proposed for the building.
