요약
병목현상은 많은 피난인들이 출구나 복도를 지나가려하게 되면 생기는 현상이다. 병목현상으로 인해 시간의 지연이 생기게 되며, 이는 건물 화재 시의 피난 예측에서 매우 중요한 요소가 된다. 피난시간 분석에서 병목현상은 유동률이라는 요소로 반영된다. 이는 시간당 단위 폭 당 통과되는 사람의 수를 나타낸다. 피난모델링에서 계산되는 유동률은 피난실험의 결과에 근접해야하며, 이에 대한 확인은 필수적인 사항이다. 본 연구에서는 유동률에 대한 피난실험의 결과와 피난모델 Pathfinder의 적용결과를 비교하여 보았다. 그 결과 피난실험과 모델링의 결과 값은 차이를 보여주고 있다. 실험의 평균값은 $4.25N/m{cdot}s$이고 시뮬레이션의 최대 값은 $1.55N/m{cdot}s$로 나타났다.
Abstract
Bottleneck occurs as many people crowd into narrow doorway or corridor. Delaying egress time is occurred by bottleneck effect, and it is very important phenomenon on the egress analysis for building fire. An analysis of egress time should includes flow rate for considering bottleneck. Flow rate is numbers of people who pass the narrow gate as door or start point of corridor per unit length and unit time. The flow rate resulted from egress modeling should be approached to the result of experiments. In this study, flow rates from modeling by 'Pathfinder' and experiments was compared. The difference between the result from egress modeling and the one from experiments was verified. The average value of experiments is $4.25N/m{cdot}s$, and the maximum average value of modeling is $1.55N/m{cdot}s$.
