Below N.A shear stress is more (rectangular) while above N.A shear stress decreases parabolically .
More shear stress means more more diagonal tension .

Shear analysis and design are NOT really concerned with shear as such.The real concern is with diagonal tension stress ; resulting from the combination of shear stress and longitudinal flexural stress.νmax = V/bd must be regarded merely as a measure of the average intensity of shear stresses in the section. The max. shear stress occurs at neutral axis with an angle of 45° Webs hear crack Flexural crack.
Web-shear crack occurs when the diagonal tension stress near the neutral axis becomes equal to the tensile strength of the concrete. Web shear cracking is relatively rare and occurs chiefly near supports of deep, thin webbed beam or at inflection points of continuous beam.
