From the experimental results presented in this study it can be concluded that the applied RSCC jacketing technique proved to be a reliable and effective method for the rehabilitation of shear-damaged RC beams. The load bearing capacity and the overall structural performance of the jacketed beams was fully restored and ameliorated with respect to the original specimens. The increase of the experimentally measured ultimate bending moment of the tested beams due to the application of the RSCC jackets ranges between 35% and 50%. This increase seems to be higher in the original beams with low amount of stirrups and to be reduced as the steel ratio of the stirrups increases. The mean value of the flexural strength of the jacketed and the original beams is 24.5 kN-m and 17.3 kN-m, respectively. Further, the ultimate shear load of the jacketed beams ranges from 39.7 kN to 42.0 kN, whereas the shear capacity of the original beams is approximately 30% lower and ranges between 27.9 kN and 30.9 kN. However, the measured average shear stress of the jacketed and the original beams is 1.14 and 1.32, respectively, since the cross-sectional dimensions of the jacketed beams were enlarged.
