An Experimental Study on Establishment of Classification System of Fire Resistance for RC and SRC Columns
Jisun Park
Abstract
The current building code for fire-resistance construction provides for a uniform standard of max. 3 hours fire resistance performance considering only structure type in building. Therefor it leads to unreasonable design fire resistant design regardless of the recent variety and complexities in building. In addition, substantial amount of time has passed since the enactment of this code, which is unable to adequately reflect the revisions to the KS fire resistance testing methods made in 2000. As a result, there is a need to confirm the performance of the current building code for fire-resistance construction. Accordingly, in this study, fire test with loading was performed for reinforced concrete and steel framed reinforced concrete columns, the results of which were compared with current domestic and overseas fire resistance standards to propose a system of more narrowly segmented fire resistance ratings.
Key Words: Fire Resistance Construction; Column; Fire Resistance Performance; Classification System
요지
현행 법정내화구조는 구조방식에 따라 획일적으로 최대 3시간의 내화성능을 규정하고 있어 최근의 다양하고 복합화된 건축물을 조건을 반영한 합리적인 내화설계를 반영하지 못하고 있는 실정이다. 뿐만 아니라 법 제정이후 상당한 시일이 경과하여 2000년 개정된 KS 내화시험 방법에 따른 법정 내화구조의 성능확인이 충분히 이루어지지 않고 있어 이에 대한 개선이 필요하다. 이에 본 연구에서는 철근콘크리트 및 철골철근콘크리트 기둥을 대상으로 재하 내화시험을 수행하고 그 결과를 현행 국내외 내화기준과 비교분석하여 보다 세분화된 내화성능 등급을 제안하였다.
핵심용어: 내화구조; 기둥; 내화성능; 분류체계
