Evacuation Simulation Considering Fire Spread and Occupants Distribution

Abstract

A fire simulator and an evacuation simulator are used separately to diagnose the safety of a large building. However, it is hard to diagnose the safety of a building using them, because they don't reflect the movement of pedestrian under fire. This study suggests an evacuation simulation considering the movement of pedestrians and fire spread. it applied the fire spread data of the fire dynamics simulator (FDS) to the floor field model (FFM) and models that a pedestrian recognizes a fire and takes a detour to a safe route. Simulations were performed under various scenarios and it was showed that the number of evacuees at each exit varied by the presence and location of fire as results.
