A crucial phenomenon that has an impact on the structural behavior and integrity of reinforced concrete parts is shear in beams. If internal stresses caused by shear forces are not appropriately handled in the design, shear failure may result. Shear forces act perpendicular to the longitudinal axis of the beam. For beams to function safely and successfully in various structural applications, shear pressures must be understood and effectively managed. The main factors relating to shear in beams are summarized in this abstract. It emphasizes the significance of taking shear forces into account while designing, covers the mechanisms of shear failure, and investigates the many techniques used to assess and strengthen beams against shear. The beginning of the abstract highlights the importance of shear in beam design and the potential repercussions of insufficient shear reinforcement. The idea of shear flow and its connection to shear stresses in the beam is introduced. The abstract then looks into the shear failure mechanisms, such as web crippling failure, shear compression failure, and diagonal tension failure.
