Abstract

A deep beam has wide application in huge structures, offshore structures as a transfer girder, long span structures and where vertical height is limited. The load transfer in this beam get interrupt when the openings are provided, which will decrease the shear carrying capacity and its serviceability. Adequate measures should be taken for the strength in deep beam when such openings are unavoidable. From literature survey it concludes that limited studies reported on deep beam strength with circular openings. Present experimental study the behaviour and strength of the simply supported conditioned steel fibred R C deep beam having dimensions 750mm × 325mm × 75mm (L x D x b) with circular openings and beam without circular openings are tested against two-point loadings. The deflection and crack pattern are studied for RC deep beam containing steel fibre (i.e upto 1 percent). The average of six deep beams for each varying dosage of steel fibre were tested for shear capacity of beam. The experiment outcomes are collated with the theoretical formula for ultimate shear load capacity. Also, this study indicates the effective location of circular shape openings in this deep beams.
