Influences of Room Door Setting Conditions on Pedestrian Evacuation

Pedestrian evacuation in different room door conditions is simulated by using FDS+Evac.The evacuating model is constructed and three kinds of room people density are set up.Especially the influences of seven kinds of door setting forms on pedestrian evacuation are studied.The research shows that when width of door is certain,the evacuation efficiency can reach the highest if there is only one door installed.When it is needed to install two doors,the evacuation efficiency can reach the highest as the doors are set in opposite walls of the room.It is the most unfavorable for evacuation if two doors are set in the near walls.This result provides references for the design of room door setting.
