The following three types of shear reinforcement are used


Type of vertical stirrups:


- Vertical stirrups
- Bent up bars along with stirrups.
- Inclined stirrups.
Vertical stirrups
- These are the steel bars vertically placed around the tensile reinforcement at suitable spacing along the length of the beam. Their diameter varies from 6mm to 16mm.
- The free ends of the stirrups are anchored in the compression zone of the beam to the anchor bars (hanger bar) or the compressive reinforcement.
- The spacing of stirrups near the supports is less as compared to spacing near the midspan since shear force is maximum at the supports.


Type of vertical stirrups:
Bent up Bars along with Vertical Stirrups
- These bent up bars resist diagonal tension. These bars are usually bent at 45°.

Inclined Stirrups
- Inclined stirrups are also provided generally at 45° for resisting diagonal tension. They are provided throughout the length of the beam.
