Abstract
Purpose: The purpose of this study was to investigate the relationship between the minimum effective width (90cm) of the exit of the evacuation stairway installed in accordance with the Building Act and the evacuation time of all occupants using the corresponding floor from an evacuation point of view. Method: The evacuation simulation (Pathfinder) was used to investigate how the change in doorway width affects the evacuation time of occupants. Result: It was found that as the effective width of the doorway became larger than the minimum standard of 90cm, the evacuation time to the evacuation stairs was shortened. This is also proof that the effective width of the evacuation stair entrance can be appropriately applied differently depending on the number of occupants on the floor. Conclusion: In the future, in order to secure evacuation safety of occupants, it is judged that the effective width standard for the exit of the evacuation stairway considering the total number of occupants by use is necessary. In addition, it is expected that the evacuation efficiency of occupants can be greatly increased if various effective width standards for entrances are made according to the number of occupants by use through research and experiments.
