The hybrid reinforced concrete structure combine the advantages of reinforced concrete structure and FRP structure together, it could resolve the problem of the durability of RC structure and brittle failure of FRP structure. In order to investigate the flexural behavior of concrete beam hybrid reinforced with FRP bars and steel bars, 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. Mechanics characteristic, flexural capacity of normal section and deflection of hybrid reinforced beams were analyzed. The results show that the average concrete strains of different height keep plane, the flexural capacities calculate by proposed formula was close to the tested value. The load-deflection curve decreased gradually after steel bars yielded.
