This paper presents a parametric study on neutral axis growth of simply supported reinforced concrete (RC) beams. Fifteen reinforced concrete beams have been analyzed. Carbon fiber-reinforced polymer (CFRP), glass fiber-reinforced polymer (GFRP), and steel bars have been used as tensile reinforcements. Two symmetrical concentrated loads were applied to each RC beam specimen. The results show that the RC beams with under-reinforced FRP had experienced the tension failure, while over-reinforced FRP had experienced the compression failure, and all of the beams with steel reinforcement had experienced the tension failure indicated by yielding of tensile reinforcement. The results of the parametric study show that the growth of the neutral axis has been classified into three following zone: the first is the zone before crack, the second is the zone after crack, and the third is the zone after yielding of the tensile reinforcement (in case of steel reinforcement only).
