Abstract
The aim of this paper is to investigate the change of pressure differential and smoke propagation characteristics in the elevator lobby with the resident's evacuation scenarios using fire modelling technique. The results showed absolute pressures in the fire room and elevator lobby can significantly increase to cause fire door to the stairway unclosed once it is open. This is due to constant pressure differentials, the increasing reference pressure of fire lobby and pressure leak from elevator lobby to fire lobby. Smoke exhaust mechanism was needed to prevent the continuous pressure rise in the living room. Over 200 Pa was expected upon closing the door during pressurization, which provide difficulties in opening the door for next refugee. Opening both fire door and entrance door may induce smoke flow from fire room to elevator lobby and stairway.
