Abstract

Abstract: Computer simulation of evacuation can be very helpful in building design for fire protection and reducing casualty in compartment fire. A coupling model for occupant evacuation building fires was proposed. A continuous model was composed by treating pedestrians movement as fluid movement, and by using Smoothed Particle Hydrodynamics method to discretize this continuous model, the model was transformed into a particle system. A method for coupling FDS into the occupant evacuation model was proposed, and the amounts of smoke density and smoke charge of pedestrian were used to determine the move direction of a pedestrian and to estimate whether a pedestrian incapacitated or not. The proposed model can simulate the phenomenon of evacuation more real and reasonable.
