Abstract
Deep beams are widely used as transfer girders in offshore structures and foundations, walls of bunkers and load bearing walls in buildings. The load transfer in the deep beam get interrupt when the openings are provided, which will decrease the shear carrying capacity and its serviceability. Adequate measures should be taken against the strength of deep beam when such openings are unavoidable. Literature shows there are limited studies reported on deep beam strength with circular openings. The present experimental study deals with the ultimate strength and behaviour of simply supported steel fibre reinforced concrete deep beams having dimensions 750mm×325mm×75mm L x D x b with and without circular openings were tested under gradually increasing two point loading. The deflection and crack pattern are studied for deep beam with the influence of steel fibre content i.e. from 0 to 1 percent . The average of six deep beams for each percentage of steel fibres were tested for shear carrying capacity of beam. The experimental results are compared with the theoretical formula for ultimate load carrying capacity. Also, this study indicates the effective location of circular opening in the deep beams.
