What is Shear Reinforcement ?

Shear Reinforcement is reinforcement that is designed to withstand shear or diagonal tension stresses.

Why are Shear Reinforcements necessary ?

Shear reinforcements, also called stirrups, are used to increase the shear resistance of reinforced concrete beams and also to change the mode of failure to a more ductile failure
