The purpose of this paper is to investigate the flexural behaviour of concrete beams with deformed steel bars and FRP bars for reinforcement. From experimental and analytical works, stiffness, crack, strength, and deflection behaviour was analysed and compared with ACI318 and ACI440. There were six specimens, which were tested by the variables of reinforcement combination (steel-steel, steel-GFRP, steel-CFRP) and concrete strength (40MPa, 60MPa). Test results showed that specimens with steel-FRP reinforcements had two times higher strength than the specimens with steel-steel reinforcements and that deflection of specimens was similar. Nominal flexural strengths of specimens by ACI318 and ACI440 were 113 similar to 142% of flexural strengths by the test. From finite element analysis, the reliability of the analysis was demonstrated by comparison between appropriate analysis model and test results.[GRAPHICS].
