An Experimental Study on Establishment of Classification System of Fire Resistance Roof Structure
Dongho Choi, Heewon Seo
Abstract
To minimize the damages under fire conditions in buildings, the main structural members of buildings shall be fire-resistance-rated structural members. For the roof which is one of the main structural members, the relevant authority only specifies the prescriptive fire-resistance-rated roof frames whose fire resistance performance has been checked by the relevant authority in building laws at present. But, these prescriptive fire-resistance-rated roof frames don`t properly reflect the recent construction materials and the technical development of methods of construction as a long time has passed. Consequently, it is needed to reset the fire resistance performance through the performance evaluation for the roof constructions specified as the present main structural member and the prescriptive fire-resistance-rated construction. This study was intended to give the fundamental materials that prescriptive fire-resistance-rated roofs are departmentalized as each structure by evaluating the fire resistance performance of the roof construction specified as the present main structural member and the prescriptive fire-resistance-rated construction.
Key Words: Fire resistance rate; Fire resistance performance; Fire resistance rated roof; Establishment of classification system
요지
건축물은 화재시 그 피해를 최소화하기 위해 건축물 주요 구조부를 일정 수준의 내화구조로 시공하고 있으며, 이러한 주요 구조부 중 하나인 지붕의 경우 현재 지붕틀에 대하여만 내화성능을 정부에서 확인하여 인정한 법정내화구조로 규정하고 있다. 또한 이경우도 규정된 후 상당한 시일이 경과되어 최근의 건축재료 및 공법의 기술발전을 적절히 수용하지 못하고 있는 실정이다. 이에 따라 현재 주요구조부와 법정내화구조로 규정된 지붕구조에 대한 성능확인 등을 통한 내화성능을 재설정할 필요가 있으며. 이에 본 연구에서는 국내의 주요구조부와 법정내화구조로 규정된 지붕 구조를 대상으로 내화성능을 평가하여 내화구조를 세분화한 기초자료를 제시하였다.
핵심용어: 내화등급; 내화성능; 내화구조 지붕; 분류체계 설정
