Abstract
Reinforced concrete (RC) beams are significant structural members in load transferring process in structural skeleton. The load carrying capacity of beams may be decreased by many reasons such as design or execution errors; or difference between the designed and actual loads. To overcome this problem, various repairing techniques can be used. Repairing with steel fiber-reinforced concrete (SFRC) jackets can enhance the cracking, ultimate loads and stiffness. It is also capable of decreasing the induced deformations. Moreover, it has many advantages over the other methods of repairing such as the reduced thickness of the jacket, fire resistance and invulnerability against corrosion. Most of the previous studies on strengthening and repairing using SFRC focused on the beams fail in flexure. The available information on behavior of RC beams fail in shear repaired with SFRC is limited. The objective of this study is to investigate the shear behavior of such beams.
