Strain-hardening cementitious composites (SHCC) have been considered as a potential material for strengthening of reinforced concrete (RC) structures. Its superior properties include high tensile strength, high ductility with multiple cracking behaviour and excellent durability. In this study, reinforced concrete beams with different shear span-to-depth ratio (1.5:1 and 2.5:1) were cast. Thin layers of high strength SHCC were patched on both sides of the RC beams as a strengthening system. The results show that the shear capacity of strengthened group is significantly increased compared to the control group. Upon ultimate failure, the formation of stable multiple cracking on the strengthening layer restrained surface concrete from spalling. This study concludes that high strength SHCC is efficient in shear strengthening of reinforced concrete structures.
