Flexural Behavior of R.C Beams Retrofitted with Hybrid FRP(Fiber Reinforced Polymer)

Hybrid FRP(Fiber Reinforced Polymer)로 보강된 철근 콘크리트 보의 휨거동에 관한 연구

This study discusses the flexural performance of rehabilitated composite sections, consisting originally of R/C beams and subsequently strengthened by, Hybrid Fiber Reinforced Polymers(FRPs) and adhesives. Experimentations were peformed with 8 specimens to compare the rehabilitated effect of the length of FRPs, 2plies of FRPs, and 3plies of FRPs. The results show that the increase of the FRP strengthening length is effective on the flexural capacity and strength. Also, R.C beams retrofitted with hybrid FRPs are more effective on the increase of flexural capacity, strength, stiffness, and ductility than with a single kind of FRPs.
