In this study, a prediction model based on the size effect of reinforced concrete members was established to investigatethe shear strength of recycled aggregate reinforced concrete beams. The main variables of the prediction model are thetensile reinforcement ratio, the effective depth of the beam, the beam width, the concrete compressive strength, and theshear span-to-depth ratio. Measurements of 408 normal coarse aggregate concrete beam specimens and 10 recycled coarseaggregate concrete beam specimens were investigated. The means between experimental values and prediction modelvalues of all the test data for α = 100 (normal beam: a/d > 2.5) and α = 103 (deep beam: a/d 2.5) were 1.07 and 1.0,respectively. In addition, the mean for recycled aggregate reinforced concrete beams was 1.06 with the standard deviationof 0.18. This result was used to predict a more accurate value by applying the correction coefficient for the recycledaggregate to the normal concrete shear proposal equation and reflecting the change in shear strength according to theeffective depth of the beam. The results of this study indicate that the prediction model was well matched to theexperimental data.
