Abstract: This paper presents a study of shear behavior of reinforced concrete beam. Generally, shear reinforcement of concrete beam consists of rectangular shape stirrups. when replacing the traditional stirrups by continuous spirally and triangular shape stirrup’s the increase shear carrying capacity of spirally shape stirrups. The spirally shape stirrups reduce the labor cost as well as crack pattern. In this research paper the theoretically shear carrying capacity of rectangular shape stirrups as per design IS456:2000 and experimental shear carrying capacity of rectangular shape stirrups is obtained and that value compared to the spirally and triangular shape stirrups. The present experiment carries 27 beam having cross section 700mm x 150mm x 150mm each set consist 9 beam of rectangular, spirally and triangular shape shear reinforcement with spacing 70mm, 90mm, 110mm. all the beam was tested using four-point loading after 28 days curing. The test result include shear carrying capacity, load-deflection curve, crack pattern. Take a test after 28 days the spirally shear reinforcement improved shear carrying capacity as well as ductility of beam compared to the rectangular and triangular shape stirrups. Hence spiral shear reinforcement shows better result as well as crack performance also deflection at mid span.
