    Abstract
  • The flexural properties of four continuous reinforced concrete(RC)beams strengthened with near-surface mounted(NSM)mixing fiber reinforced polymer(FRP)tendons were studied by static test.The influence factors of bearing capacities of test beams were analyzed by finite element analysis(FEA)software, such as strength of concrete, initial load, elastic modulus and content of FRP tendons.Analysis result indicates that the reinforcement effect without debond between FRP tendons and concrete is significant.Compared with unstrengthened RC beam, the yield load and ultimate load of strengthened RC beam can increase by 31%and 56%respectively.When concrete strength, elastic modulus and content of FRP tendons increase, the yield load and ultimate load can increase by 38% and 17% respectively.When initial load increases, the yield load and ultimate load can decrease by 6% and 24% respectively.For test RC beams, the mean ratio of simulation and test values for the yield load is 0.969, 0.962 for the ultimate load, 1.104 for the midspan yield deflection, 1.024 for the midspan destructive deflection, and the trends ofsimulation load-deflection curves are basically consistent with test curves, so FEA result is in good agreement with test result, and FEA can accurately simulate the mechanical properties of test beam.
