Abstract
This study is based upon the experimental investigation of shear reinforcement used in the reinforced concrete beams by using swimmer bars. In practice, vertical stirrup system is used in order to enhance the shear carrying capacity of beams. However in this research, a new type of shear reinforcement known as swimmer bars (inclined at an angle of 45°) are used in beams. Swimmer bars have more shear carrying capacity than vertical stirrups and can be placed with larger spacing. The effectiveness in terms of cost and shear carrying capacity is studied by casting beams in laboratory. The beam consisting of swimmer bars showed much more stiffness than beam with vertical bars. Also the ultimate load carrying capacity of swimmer bars is more than the vertical stirrups. Less number of cracks is formed in beams having swimmer bars.
