Flexural behavior of EB-FRP (externally bonded FRP) and HB-FRP (hybrid bonded FRP) strengthened RC beams is studied in this paper. Three beams test and finite element analysis was conducted. Basis on appropriate material model, blunt crack model, modelling of steel and FRP and their bond behavior, numerical finite element model is verified by comparing with model test results. The results show that failure mode of EB-FRP strengthened beams is plate end interfacial deboning. Failure mode of HB-FRP strengthened beams is shear failure. Compared with the beams without FRP strengthening, the flexural capacity increased by 20% for HB-FRP than EB-FRP. The FRP stress is about FRP strength for HB-FRP and steel fasters effectively prevent FRP deboning.
