Recently developed high strength aluminum alloys (AA) have desirable characteristics that make them
attractive as externally bonded strengthening materials. This paper investigates the potential of using
AA plates for shear strengthening of reinforced concrete (RC) beams. Five shear deficient RC beams were
externally strengthened using AA plates with different orientations. It is observed that the shear capacity
of the strengthened beams has increased in the range of 24%–89% compared to the un-strengthened
beam. Shear capacity of the strengthened beams was also predicted using the ACI440, FIB14, TR55 and
SMCFT design guidelines with the later one giving the most accurate predictions.
