Abstract

The ventilation system for the efficient operation of the building services systems in the ventilation plan of super high-rise buildings is used to combine smoke control systems. This study evaluated models of super high-rise buildings with four basement levels and 59 stories and investigated the pressure distribution of each floor by the smoke driving forces by numerical analysis. The smoke driving forces on the building of analytical model was analyzed to determine the effects of the ventilation plan and smoke control plane. In addition, when a combination with ventilation and smoke control of the kitchen ventilation damper in the ventilation plan of analysis model building was designed based on the these results, the relationship between the opening and closing force of the damper and smoke driving combined forces to act on the design pressure of the damper by a motion analysis simulation. The driving units of the damper were selected from the analytical results.

초고층 건물의 환기계획에서 설비의 효율적인 운영을 위해 환기설비는 제연설비 겸용으로 사용되고 있다. 본 연구에서는 지하 4층 지상 59층의 초고층 건물을 분석모델로 선정하고 수치해석을 통해 연기이동력에 의한 층별 압력분포를 검토하였으며, 분석모델 건물에서의 연기이동력이 환기 및 제연에 미치는 영향을 규명하였다. 또한 이들 결과를 바탕으로 분석모델 건물의 환기계획에서 주방용 환기댐퍼를 환기-제연 겸용으로 설계할 때 연기이동의 복합력과 요구되는 댐퍼의 개폐력과의 관계를 운동해석 시뮬레이션을 통해 결정하였고, 그 결과로부터 적합한 댐퍼의 구동장치를 선정하였다.
