Abstract

In recent years, many efforts have steadily been allocated to develop a new deck system in terms of its materials and structures in order to make up for the shortcomings of reinforced concrete deck. This study implemented and analyzed the verification for concrete composite beam with perfobond FRP as a permanent formwork and the tensile reinforcement, using non-linear finite element analysis program. Approximately 8-15% difference of ultimate failure load between numerical and experimental results were found and showed a similar figure of strain distribution in failure state.

최근 철근 콘크리트 바닥판의 단점을 원천적으로 보완할 목적으로 재료적 측면과 구조적 측면에서 새로운 바닥판 시스템을 개발하려는 노력이 계속 되어 왔다. 본 연구에서는 퍼포본드 FRP를 영구거푸집 및 인장 보강재로 이용한 콘크리트 합성보에 대해 비선형 유한요소해석 프로그램을 활용하여 검증해석을 실시하고 이를 분석하였다. 실험결과와 비교해서 극한파괴하중의 경우 약 8-15% 내외의 차이를 보여 주었으며, 파괴 시 변형도 분포형태는 실험과 유사한 경향을 보여주었다.
