The design shear stress (τc) in reinforced cement concrete depends on
1) Characteristic strength of concrete.
2) Percentage of steel Reinforcement.
Whereas, the maximum shear strength (τmax) of reinforced cement concrete depends on the grade of concrete only.
As per IS code, Stipulates the maximum shear stress of reinforced concrete in beams τcmax as given below in Table. Under no circumstances, the nominal shear stress in beams τv shall exceed τcmax given in the table for different grades of concrete.
