Interface Debonding of Reinforced Concrete Beams Strengthened with Carbon Fiber Sheets

탄소섬유시트 보강 철근콘크리트보의 계면박리에 관한 연구

The strengthening method with CFS(Carbon Fiber Sheet) to reinforced concrete structures has a fatal defect. Strengthened beams have been almost failed far below their ultimate strength due to interface debonding failure between the surface of concrete and CFS. The purpose of this study is to investigate the failure mechanism and failure behavior of strengthened RC beam using CFS.
