In order to investigate the flexural behavior of concrete beam reinforced with 500MPa fine grain high steel bars, four rectangle cross-section concrete beam subjected to static bending test were made. Mechanics characteristic, flexural capacity of normal section, crack and deflection were analyzed according to current related China code. The results show that the flexural behavior of concrete beam reinforced with 500MPa fine grain high steel bars is similar to normal concrete beam, the average strain of concrete section keep plane; flexural capacity and average crack spacing could still calculated by current code for their values coincide well with tested value; however, deflection values of the specimens calculated by current related China code are smaller than corresponding tested value; under the state of serviceability, crack width and deflection of the specimens were found not to meet the requirement of current China code while the design value of yield strength of 500MPa fine grain steel bar was taken more than 360MPa.
