Design of Shear Reinforcement in a beam
The beam is failed by the diagonal tension in which the cracks start from support and extend upto a distance equal to effective depth and making an angle more or less than 45 degrees.
Here are the steps for the design of Shear Reinforcement in a beam:
Step one
Nominal shear stress
Tv = Vu/bd
Where, Vu = shear force due to design load
b = width of the beam
d = depth of the beam
Step two
Percentage of steel
Percent steel = Ast/bd x 100
