Abstract
선진외국에서는 화재 공학적 이론식을 적용한 대안적 성능설계 방법을 통하여 다양한 구조물의 내화설계를 수행하여 왔다. 그러나 국내의 경우, 강구조물에 대한 대안적 내화성능 설계 절차만을 제시하고 있을 뿐 실제 건축물을 대상으로 성능설계를 진행한 사례는 없는 것으로 나타났다. 본 연구는 기존 연구결과물로 제시되었던 대안적 내화성능설계 프로그램을 이용하여 실제 강구조 건축물의 내화성능을 평가하기 위하여 수행되었다. 대안적 내화성능 평가로부터 국내 강구조 건축물의 경우, 내화설계에 있어 과잉설계 된 것으로 파악되었다. Advanced foreign countries have performed the fire resistance design of buildings by the alternative performance design methods, which are based on fire engineering theories. However, in the case of South Korea, the process on the alternative fire resistance performance design has only suggested without any applications for real steel structures. This study was performed to evaluate the fire resistance performance of a steel building using the fire resistance performance design program, which was developed in the former research. From this study, it was obtained that the fire resistance design was over designed for the steel building in South Korea.
