ABSTRACT
This experimental works aims to study (i) the behaviour of Fibre reinforced Concrete Beams(FRCB) without shear reinforcement (ii) the possibility of using steel fibers as shear reinforcement in reinforced concrete beams (RCB). Conventionally the beams are designed with shear reinforcement/ stirrups along with the tensile reinforcement which is expensive because of the labour cost associated with reinforcement installation. Hence, experimental works are carried out to find alternative solution to take care of shear forces without shear reinforcement. The steel fibres of aspect ratio 66.67 were in co-operated in the designed mix with fibre volume fraction (1.0and 1.5%) to study the behaviour of FRCB under two point lading. The test results showed that, the shear reinforcement is not required for FRCB of 1.0% and above upto shear stress of 1.77N/mm2 for concrete of cube strength 36.66 N/mm2 at 28days.
