본 연구의 목적은 성능적 내화설계를 기반으로 한 철근콘크리트 기둥의 내화성능 평가를 최종 목표로 철근콘크리트 기둥의 열전달 해석을 통한 온도분포와 재하가열실험을 통한 수축량으로 적정 축력비를 도출하여 성능설계를 위한 기초 자료로 활용하고자 하는데 있다. 편심이 전혀 없는 순수축력을 기준으로 축력비 0.30, 0.35, 0.40, 0.47을 재하한 결과, 0.40 이상의 축력비를 확보하여야 내화성능을 만족할 수 있다고 판단하였다. |
| Abstract |
|
This study, to evaluate the technology of the fire resistance design of Reinforced Concrete columns based on fire resistance performance design, was suppose to use as basic data for performance design through a measure of temperature and deformation using heat transfer analysis and Heat-load test of the Reinforced Concrete columns as parameter is the axial load ratio. In accordance with axial load without eccentricity, the load ratio of 0.30, 0.35, 0.40 and 0.47 were imposed on columns. As a result of this study, 0.40 or more of axial load ratio can be ensured that the fire resistance performance was considered satisfactory. |
