초록

가연물의 증가는 건축물 화재의 발생 위험성과 재해발생 규모를 점차적으로 증대시키는 요인이 되고 있다. 따라서 강구조 건축물의 화재에 대비한 기술개발이 요구되었으며, 이 결과로 내화강재가 개발되었다. 본 연구에서는 FR 490강재의 고온 시 기계적, 열적 특성을 실험적으로 평가하고, 이 결과를 상온 시 구조적 내력이 동일한 용접구조용 강재인 SM 490과 상호 비교함으로써 고온 시의 내력유지 성능이 우수함을 확인하였다.

Fire at building can occur enormous damages to life, properties, and environment and the risk of fire breakout is going up higher because of application of combustible materials than before. Therefore, the steel industries are trying to develop fire resistant steel in order to sustain the load bearing capacity of steel structures during fire situation. In this paper, to give the basis data-bases for evaluation of structural stability of steel structures applied fire resistant steel, FR 490, the tests of mechanical and thermal properties at high temperature were conducted and the comparisons are done with the SM 490 that has the same mechanical one.
