The shear reinforcement should form an angle of between 45 and 90 degrees to the longitudinal axis of the structural element.
The ratio of shear reinforcement is given by: ρw = Asw / (s bw sin α) where
Asw is the area of shear reinforcement within length s,
The minimum shear reinforcement ratio is given by
ρw,min = (0,08 fck0,5) / fyk
The maximum spacing between shear assemblies should not exceed
sl,max = 0,75 d (1 + cot α)
The transverse spacing of the legs in a series of shear links should not exceed st,max:
st,max = 0,75 d ≤ 600 mm

The minimum shear reinforcement ratio is given by
ρw,min = (0,063 fck0,5) / fyk
