SIDE FACE REINFORCEMENT IN BEAMS AS PER IS 456 (INDIAN CODE)

For beams exceeding the depth of 750 mm Side Face Reinforcement is provided to ensure lateral stability as well as confinement to increase the ductility of the beam member. Moreover, this additional side face reinforcement which is not included in load sharing mechanism also helps in dissipation of additional forces.
In general practice as per IS 456:2000 clause 26.5.1.3 gives the guidelines for the provision of side face reinforcement in beams in which web thickness is greater than 750 mm. kindly refer attached image for further clarification.

Apart from above stated general guidelines, if the concerned beam member is subjected to considerable lateral forces than it shall be analyzed as per the conventional method which we use for forces along the depth the same shall be used for calculation of moments due to the forces applicable along the width of the member.
