본 연구에서는 화재 시 효과적인 연기배출을 위해 국내 건축법에서 규정하고 있는 배연창이 고층건물의 연돌효과 및 배연성능에 미치는 영향을 분석하기 위해 현장실험과 모델링 해석을 병행하였다. 현장실험은 배연창이 설치된 고층건물을 대상으로 정상조건 및 배연창 개방조건에서 외기온도에 따른 계단실, 부속실 및 복도에서의 압력분포 측정을 통해 연돌효과를 분석하였다. 모델링 해석에서는 연기유동 해석용 네트워 크모델인 CONTAMW을 이용하여 모델링결과 및 실험결과의 비교분석을 통한 보정기밀도를 적용하여 이 상적인 대상건물을 구현하고 배연창의 배연성능을 평가하였다.


Natural smoke ventilator is one of domestic prescriptive methods to be used to exhaust smoke in case of fire in a high-rise buildings. The goal of this study is to evaluate the stack effect and the smoke exhaust performance in high-rise buildings with the opening of natural smoke ventilators using computer modeling technology, thus to estimate its effectiveness as a tool of smoke exhaust. For this purpose, the pressure differential in a domestic high-rise building with natural smoke ventilators was experimentally measured to analyze the stack effect with the closure or the opening of natural smoke ventilators and to calculate compensated air leakage of the building. Computer modeling based on experimentally measured data was carried out to estimate effectiveness of natural smoke ventilators in high-rise buildings using CONTAMW network program.
