Shear Strength of Reinforced Concrete Beams Strengthened by Fiber Reinforced Polymer

섬유보강 철근콘크리트 보의 전단강도 평가

In recent years, the use of fiber reinforced polymer (FRP) composites to repair or strengthen existing reinforced concrete (RC) structures is increasing In order to evaluate the shear strengths of RC structures strengthened by FRP composites, it is needed to understand the shear failure modes of these structures. This paper presents a rational equation to distinguish the shear fail modes of RC structures strengthened by FRP composites using the compatibility aided truss models.
