Types of shear reinforcementShear reinforcement, also known as web reinforcement may consist of any one
of the following systems (Cl. 40.4 of the Code)• stirrups perpendicular to the beam axis;
• stirrups inclined (at 45° or more) to the beam axis; and
• longitudinal bars bent-up (usually, not more than two at a time) at 45° to 60° to
the beam axis, combined with stirrups.

The most common type of shear reinforcement is the two legged stirrup, comprising a
closed or open loop, with its ends anchored properly around longitudinal bars/stirrup
holders (to develop the yield strength in tension).
