초록

오늘날 인간의 삶의 질 향상과 다양한 욕구를 충족시키기 위한 건축물은 대형화, 고층화, 다양화되는 추세이며, 이에 따른 화재의 발생빈도 및 잠재적인 위험요소가 증가되고 있다. 특히, 화재발생 시 수직으로의 연소확대 위험성이 증가되어 재실자의 피난시간이 지연되는 문제점이 있다. 이러한 문제점을 극복하기 위해서는 화재를 조기에 감지하고 건축물의 구조 등을 감안하여 위험순위에 따른 화재 경보방식을 적용할 필요가 있다. 따라서, 본 논문에서는 수직 연소확대의 위험성을 많이 내포하고 있는 2가지 구조인 전면형 이중외피 구조와 계단 구조에 대해 수직 연소확대 특성을 설명하고, 국내 외 화재경보방식을 비교 검토한 후 FDS 이용하여 연기밀도, 가시거리, CO 농도를 비교 분석하여 각 구조에 적합한 화재경보방식을 제안하였다.

Today, high-rise buildings expected to meet various needs and improve the quality of frequency of fire and the potential risks are increasing. In particular, the fire spread risk in the vertical direction is increasing. As a result there is a problem with delays in the evacuation time of occupants. To overcome this problem, there is a need to consider the structure of the building and develop a system for the early detection of fire by applying a fire alarm system according to the risk ranking. Therefore, this paper describes the vertical fire spread characteristics of a multistory double-skin and stairs structure with risk. The data were compared with that from the national and international fire alarms as well as with. smoke density, smoke detectors, visibility, and CO concentration using FDS. A fire alarm system for each structure is proposed.
