Study on the Flexural Capacity of Concrete Beam Hybrid Reinforced with FRP Bars and Steel Bars

摘要

Two Nominal reinforcement ratios and three failure modes were put forward according to the characteristic of FRP bar and the criterion of appropriate hybrid reinforcement beam was given. Flexural capacity of appropriate hybrid reinforcement beam was analyzed according to the theory of reinforcement concrete and flexural capacities simplified calculate formula of appropriate hybrid reinforcement beam was proposed, three different area ratio of FRP bar to steel bar hybrid reinforced concrete beams, one FRP reinforced concrete beam and one reinforced concrete beam static flexural test were made and the tested results show that the flexural capacities calculate by proposed simplified formula was close to the tested value.
