Abstract : As per Code of Indian Standards, a concrete having a compressive strength greater than or equal to 65 N/mm2 is referred to as a high strength concrete. High strength concrete has many favorable properties, but it is a brittle material and has a low rate of increase of tensile strength due to which it is not of great use in earthquake-prone areas. The best method to improve the flexural shear behavior is to incorporate fibers in concrete at the required proportions. This paper investigates the flexural shear behavior of high strength concrete beams by replacing traditional shear reinforcements with steel fibers only in the shear span. The effect of varying volume fractions of fibers (0%, 0.5%, and 0.75%) is also studied. It was found that the brittle failure was converted to ductile failure by fiber addition only in shear span. The load carrying capacity, compressive strength and split tensile of high strength concrete increased with increase in fiber volume.
