Simulation Study of Personnel Evacuation in Fire Scenarios of Old School Buildings
In order to improve the emergency evacuation capability of an old school building under fire scenarios,a fire evacuation model of an old school building is developed.The PyroSim software is used to build a fire dispersion model to simulate and analyse the changes of smoke visibility temperature and CO at the safety exit of the fire floor in the school building under the condition of mechanical smoke exhaust,automatic sprinkler and whether the windows of the fire room are open or not.The simulation of the exit status and evacuation of people has been carried out in conjunction with Pathfinder software to obtain the required safe evacuation time when all the people are evacuated.The case study shows that the evacuation efficiency of the old school building is reduced by 12.1％without sprinklers,and the evacuation of people is in a dangerous state without mechanical smoke extraction,having more exits has less impact on improving the efficiency of evacuating people.
