초록

FRP 판을 콘크리트 구조물의 거푸집 및 보강재로 이용하기 위한 기본적인 실험을 수행하였다. FRP 판과 콘크리트가 합성 효과를 발휘하기 위해서는 두 재료간의 부착이 중요한 요인 중의 하나이다. 이러한 부착을 확보하기 위하여 FRP 판에 두 가지 크기의 골재를 일반적으로 건설 현장에서 많이 사용하는 에폭시를 이용하여 부착 하였다. 콘크리트 보는 FRP 판만으로 인장 보강하였고 추가적인 휨 및 전단 보강은 하지 않았다. 비교를 위해 한 비교 실험 시편은 FRP 판에 골재를 부착하지 않고, 다른 한 비교 실험 시편은 FRP 판 대신에 종래의 철근으로 보강하여 실험하였다. 모든 콘크리트 보의 실험은 보의 중앙에 집중하중을 파괴까지 재하하였다. 실험 결과는 현행 ACI 318(2005)과 ACI 440(2006)과 비교 분석하였다. 본 연구 결과 FRP 판을 콘크리트 구조물의 거푸집 대용 및 인장 보강재로 충분히 활용할 수 있는 가능성을 보여주었다.

We perform an experimental study of concrete beam with pultruded fiber reinforced polymer(FRP) plank using as a permanent formwork and the tensile reinforcement. A satisfactory bond at the interface between the smooth surface of the pultruded plank and the concrete must be developed for the FRP plank and the concrete to act as a composite structural member. Two kinds of aggregate were bonded to the FRP plank using a commercially available epoxy. No additional flexural or shear reinforcement was provided in the beams. For comparison we test two types of control specimen. One control did not have any aggregate bonded to the FRP plank and the other control had infernal steel reinforcing bars instead of the FRP plank. The beams were loaded by central patch load to their ultimate capacity. The experimental results were compared to current ACI 318 (2005) and ACI 440 (2006) code predictions. This study demonstrates that the FRP plank has the potential to serve as formwork and reinforcing for concrete structures.
