Abstract: Based on the tests of RC beams strengthened with hybrid fiber sheet(HFS),the influence and effectof strengthening with carbon/aramid fiber sheet(C/AFS) on flexural strength for RC beams are analyzed.The variation of cracking and ultimate load,stiffness,etc.is studied.The experimental and numerical results calculated with finite element method show that flexural strength and stiffness of RC beam strengthened with HFS are obviously improved.Hybrid strengthening method is of feasibility and high efficiency.
