Abstract: This research provides experimental data on comparison between the inclined bars and vertical stirrups used as shear reinforcement. Different forms of shear reinforcement are induced and studied in this research. Since shear failure occurs at an angle of 45º, therefore if it can be counteracted using an inclined stirrup, then there may be a chance to reduce the crack propagation in flexure members. Inclined bars are generally provided in beams since the principle tensile force acts in an inclined direction. They are provided throughout the length of the beam. Hence different forms of stirrups such as truss model, inclined stirrups and bracing type are used. Total 8 beams are casted in which two are designed with conventional stirrups, two with truss type and two with bracing type. These forms are analyzed under different loading conditions such as three point and four point loading. From the results obtained, crack pattern, strength characteristics and strain were observed and compared with conventional stirrups induced in beams. It has showed that the beam with inclined bars has showed improvement in strength characteristics compared to the beam with conventional stirrups.
