This study reviews past literatures relevant to concrete beams using recycled aggregates (RAs) and investigate existing shear design equations for reinforced concrete (RC) beams. Then, a simplified, emprical design equation to determine the shear strength of high strength RC beams with RAs is proposed and compared with existing equations. The analysis indicated that the proposed equation provided the most accurate estimated of strength of high strength concrete beams with RAs.
