An Analysis of Interface Debonding Failure on Reinforced Concrete Beams Strengthened with Carbon Fiber Sheet

탄소섬유쉬트로 보강된 철근콘크리트보의 계면박리해석

The purpose of this study is to analyze the interface debonding failure on RC beams strengthened with carbon fiber sheet(CFS). The behavior of damaged RC beams strengthened with CFS is analytically investigated using both linear elastic fracture mechanics (LEFM) approach and the finite element method. This study includes the investigation of the separation mode by interface fracture of the strengthening materials due to the interfacial shear and normal stresses.
