Abstract
최근 다양한 형태의 막구조물의 건설이 증가추세이지만 막구조물에 적합하지 않은 내화기준이 적용되어 활용성이 위축되고 있는 실정이다. 그렇기 때문에 막구조물의 건설 활성화에 맞추어서 이에 대한 내화기준의 제 개정이 필요한 상황이다. 따라서 본 연구에서는 일반적으로 많이 사용되는 막재료(ETFE, PVF, PTFE)를 선정하여 막구조물에 화재가 일어났을 때, 시간이 변화함에 따라 온도가 올라가는 막재료의 물리적인 특성 변화와 발열량과 막재료 설치높이와의 상관관계를 파악하여 막구조 내화기준에 기초 자료로 활용하고자 한다. Various form of membrane structures are being built in recent years. However, there is no appropriate fire proofing standards which can be applied each specific membrane structures. Therefore, existing fire protection standards are in establishment state and they need to be revised. In the current study, commonly used membrane materials(ETFE, PVF, PTFE) has been selected to investigate its fire resistance behavior with the change of fire duration time. In addition to this, heat generation rate of the membrane materials in correlation with the height of membrane has been investigated. And these fire combustion characteristics of membrane materials can be used in future practice for the fire prevention regulations of membrane structures.
