Download Solution PDFExplanation:
The shear strength of reinforced concrete with the reinforcement is restricted to some maximum value τcmax depending on the grade of concrete.
Table 20 of IS 456
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.
