Mpa * Design according to M.O.M.R.A. (5.8.2)

Mpa bv = Web width - 0.25 * diameter of duct * Number of ducts at that level

Mpa Ac =Area of concrete on the flexural tension side

Mpa dv = effective shear depth =0.72 x h or 0.9 x d which is bigger

Mpa es = strain in non-prestressed longitudinal tensionreinforcement

Mpa V c =0.083 x b x bv x dv x fc '

mm20.083 x bv x s x fc '

mm fy

angle of inclination of diagonal compressive stresses (º)

mm factor relating effect of longitudinal strain on the shear capacity of concrete
