강섬유를 혼입한 고강도 콘크리트 보의 탄소섬유쉬트 보수ㆍ보강에 관한 연구 = A Study on Repair and Rehabilitation of High Strength Reinforced Concrete Beams Mixed Steel Fibrous with Carbon Fiber Sheets

다국어 초록 (Multilingual Abstract)

The carbon fiber reinforced plastic bonding method is widely used in reinforcing the existing concrete structure among the various methods. The repair of initiate loaded reinforced high-strength concrete beams mixed steel fibrous with epoxy bonded Carbon Fiber Sheets(CFS) was investigated experimentally. The CSF is attractive for application due to its light weight, the high tensile strength, good workability, resistance to corrosion and good appearance after repair. The CFS thickness and length were varied to assess the peel failure at the curtailment of CFS The behaviour of the repaired beams was represented by load-longitudinal steel strain relation and failure modes were discussed The test results indicate that CFS is very effective for strengthening the demand beams and controlling deflections of reinforced high strength concrete beams mixed steel fibrous happen diagonal crack, the increase in the number of CFS layers didn't effect the increase in the strength of beams
