초록

국내의 내화성능평가는 대부분 사양적설계 방법인 품질시험을 통해 이뤄지고 있다. 하지만 시험 특성상 많은 비용과 시간을 요구하며 다양한 건축구조에 대한 내화성능평가에는 어려움이 많다. 따라서 본연구에서는 성능적 설계를 위한 연구로 유한요소 구조해석 프로그램인 ABAQUS를 사용해 H형강 휨재를 대상으로 변수에 따른 열응력 해석을 통해 내화성능을 검토하며, 하중비별 한계온도를 제안한다.

The domestic fire resistance performance test is conducted as a prescriptive design method such as quality test. In quality test there are 2 methods, unloaded fire resistance test and fire resistance test under load. In realistic, these tests, however, have problems with expense, time and diversity of structure. This study reviewed fire resistance performance of H-beam flexural member by thermal stress analysis using finite element ABAQUS program. This research is for the performance-based design reviewing applicability of domestic standard. As a result of this study, limit temperatures per each load ratio provied for proper performance of fire resistancy.
