The flexural failure behavior of RC beams made of different kinds of concrete and reinforcing materials is investigated. High strength concrete (HSC), aramid fiber and steel fiber reinforced concrete (AFRC and SFRC) and continuous fiber reinforced plastic (FRP) grid are included in addition to normal strength concrete (NSC) and ordinary steel bars. The favorable failure modes of RC beams are discussed. In the case of beams reinforced with steel bars, the minimum reinforcement ratios were 0.15% for NSC beams, 0.4% for HSC beams and 1.0% for SFRC beams in the range of this study. High performance non-metallic RC beams could be produced by combining AFRC and FRP grid.
