단면크기에 따른 철근콘크리트 기둥의 내화성능에 관한 실험연구

The fire resistance performance of reinforced concrete column with different section size was analyzed experimentally. Two types of section size, 250 x 250 ㎜ and 400 x 400 ㎜ were considered in this study. All testing procedures including specimens preparation, set-up of test equipments and measuring devices were made according to the recommendations of Korean Industrial Standard 2257-1 and 7. From the test results, it was found that fire resistance capacity of specimen with large section was higher than that of the other.
