Abstract

Abstract: For the sake of preventing fire accidents in an airport terminal building,BIM was employed to evaluate the influences of the building layout and fire extinguishing system on the fire smoke spread and personnel evacuation.BIM was applied in the terminal fire evacuation management,the operation of terminal fire-fighting system and safety of evacuees were simulated quantitatively by using two kinds of software of PyroSim and Pathfinder.Changes in smoke,heat and evacuation process were analyzed.It turns out that for the present building layout,the thermal radiation of a fire happening in the peak flow period has not a significant influence on the evacuation process even if the smoke extracting system fails to start in time,that a sudden decrease in the height of smoke is a dangerous threat to the evacuees,and that the expansion of the open space area in front of the boarding gate,removal of unnecessary indoor facilities and promotion of the linkage between fire-fighting system and boarding gate are helpful to shortening the time of evacuation.
