Research on the Safe Evacuation of Personnel in Exhibition Halls of Large Exhibition Centers Based on PathFinder Simulation
Under the set fire conditions,based on the available evacuation time obtained from FDS simulation,a simulation study of personnel evacuation in exhibition halls and small exhibition halls was conducted using the corresponding evacuation scenarios and the constructed PathFinder evacuation model.Under the premise of designing the number of users for the exhibition hall and exhibition small hall as 6 750(6 600)and 2 450 people respectively,the research results show that in the corresponding evacuation scenarios,the exhibition hall is directly evacuated to the outside through evacuation exits,the exhibition small hall is directly evacuated to the outside through evacuation exits,and the exhibition small hall is directly evacuated to the outside or adjacent zones through evacuation exits.If the fire scenario is set as automatic sprinkler system failure and mechanical smoke exhaust system activation,the necessary evacuation time for personnel is 510,455,and 543 s,and the available evacuation time for personnel is not less than 1 200 s,TRSET＜TASET.If the fire scenario is set as an automatic sprinkler fire extinguishing system,with the maximum heat release rate controlled at 2.2 MW and the mechanical smoke exhaust system turned on,the necessary evacuation time for personnel is 510,455,and 543 s,respectively.The available evacuation time for personnel is not less than 1 140 s,and TRSET＜TASET.Under the conditions of setting fire scenarios,the designed safety exits can meet the needs of safe evacuation of personnel.
