While a little research has been performed on flexural behavior of reinforced polymer concrete (RPC) beams with the compressive strength lower than 1000kg/$\textrm{cm}^2$, vary little exists in conjunction with the behavior of (RPC) 1,400kg/$\textrm{cm}^2$ or compressive strength. In this paper the flexural behavior of high strength polymer concrete beams with 1,400kg/$\textrm{cm}^2$ in compressive was evaluated. The unsaturated polyester resin was used to make polymer concrete as binder. The beams with stirrup singly/doubly were rested to examine the effect of tensile reinforcement ratio. As test results. steel ratio increased with the increased moment strength, decreased with ultimate deflection.
