Abstract

Weight-bearing building materials are substantially weakened under high temperatures, and this is evident through the collapse of structures once engulfed by fire. Currently, there is no scientific or technological process of evaluating the real-time structural stability of a building whcih is engulfed by flame. There are many building design specifications which aim to reduce the risk of fire, but little consideration given to fire officer safety while operating in a dangerous building. This paper aims to provide direction within building policy in order to ensure the safe evacuation of fire-fighters in case of an impending building collapse. This paper suggests evaluation criteria for buildings which are damaged due to fire, autilizing current information on fire-resistant building design and a fire-resistant capacity.

화재는 건축구조물을 손상시키고, 궁극에는 붕괴될 수 있어 재실자 및 소방관의 생명을 위협한다. 따라서 화재 시에 구조물 내부의 재실자 및 소방관의 안전을 확보하기 위하여 구조물 안전성에 대한 과학적이고 공학적인 분석이 요구된다. 그러나 현실적으로 화재현장에서 화재손상 건축구조물에 대한 실시간 구조물 안전성 평가, 소방활동 안전구역 설정, 붕괴 우려시 소방관 철수 결정 등에 관한 과학적이고 공학적인 평가 절차 및 방법은 전무한 실정이다. 이에 내화설계 및 화재저항성평가 이론 등을 활용하여 화재손상 건축구조물에 대한 실시간 안전성평가에 관한 절차 및 방법을 제안하였다. 물론 이러한 안전성평가 절차 및 방법은 화재초기부터 실시간 화재건물 내부 상황을 가장 잘 파악 가능한 소방관에 의하여 이루어져야 한다고 판단되어 소방관이 활용가능한 안전성평가 절차 및 방법을 제안하였다.
