Abstract

This paper presents an investigation of the strength and deformation characteristics of reinforced concrete rectangular beams failed in shear and repaired by epoxy injection.Five simply supported reinforced normal-strength concrete (NSC) beams without shear reinforcement are used. The span of the simply supported beams is 1.28 m with 100 mm wide by 200 mm deep cross section. All beams are tested under two-point loads.A method of epoxy injection is used to repair cracks in the failed-in-shear beams. Careful repair process is adopted and proved successful.The Main conclusions are: a successful repair method is used to increase or at least restore the shear capacity of beams; repaired diagonal shear cracks do not reopen after retesting, instead, new nearby diagonal shear cracks are developed and the repaired beams show a lower stiffness and greater ductility than the original beams.
