The object of this study is to clarify the effects of tensile reinforcements on flexural characteristics of Carbon Fiber Reinforced Concrete (CFRC) beams. The conventionally reinforced concrete beams and the reinforced CFRC ones with three different effective depths were tested under pure bending loads. Theoretical moment-curvature relationships for the reinforced CFRC beams were derived considering high tensile toughness of CFRC. Main conclusions obtained were as follows. 1) Cracking load of the reinforced CFRC beams was from 2.1 to 2.7 times higher than that of the conventionally RC beams with increasing of the effective depth. 2) Fairly good agreement was obtained between the theory and the experiment for momentcurvature relationships considering the effect of specimen size.
