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.
연구목적: 건축법에 따라 설치되는 피난계단 출입구의 최소 유효 폭(90cm) 기준이 해당 층을 사용하는 전체 재실자의 피난 시간과는 어떤 관계가 있는지 피난 관점에서 알아보고자 하였다. 연구방법: 출입구 폭의 변화에 따라 재실자의 피난 시간에 어떠한 영향을 미치는지를 피난 시뮬레이션(Pathfinder)을 통하여 알아보았다. 연구결과: 출입구의 유효 폭이 최소기준 90cm보다 커지면 커질수록 피난계단으로의 피난 시간이 단축되는 것을 알 수 있었고, 더불어 출입구의 너비가 일정 크기 이상 되면 피난 시간은 더는 단축되지 않는다는 사실도 알 수 있었다. 이는 해당 층 전체 재실자의 수에 따라 피난계단 출입구의 유효 너비를 적정하게 달리 적용할 수 있다는 방증(傍證)이기도 한 것이다. 결론: 앞으로는 재실자의 피난 안전성 확보를 위해 용도별 전체 수용인원을 고려한 피난 계단 출입구 유효 폭 기준이 필요할 것으로 판단된다. 더불어 연구 및 실험을 통해 용도별 수용인원에 따른 다양한 출입구 유효 폭 기준이 만들어진다면 재실자의 피난 효율성이 크게 증대될 수 있을 것으로 기대된다.
