What are Bent-Up Bars?

Bent-up bars are the main reinforcements bent at a suitable angle to act as shear reinforcement. Reinforcements are bent up to the supports where greater compressive force occurs.

What is Vertical Stirrup?

The vertical stirrup is a steel bar that is placed around the tensile reinforcement at suitable spacing along the length of the beam.
