Strengthening and Ductility Evaluation of Reinforced Concrete Beams Shear-Strengthened by Steel Plates and Glass Fiber Sheets

강판 및 유리섬유쉬트로 전단보강된 철근콘크리트 보의 보강 및 연성 평가

Shear strengthening method by steel plates and fiber reinforced polymer lamination has recently been favorably selected due to its efficiencies of duration and performance. Shear failure being brittle and difficult to predict, reinforced concrete structures must have sufficient capacity to absorb the energy for shear failure and to support temporarily the overload which may result due to the loss of shear capacity to the structure. These respects being considered, this research has carried out with the purpose of the experimental verification of the shear strengthening effect and ductility evaluation.
