5 The shear reinforcement should form an angle of between 45 and 90 degrees to the longitudinal axis of the structural element.

7 The ratio of shear reinforcement is given by: ρ,,w,, = A,,sw,, / (s b,,w,, sin α) where

11 The minimum shear reinforcement ratio is given by
12
13 ρ,,w,min,, = (0,08 f,,ck0,5,,) / f,,yk,,
14
15 The maximum spacing between shear assemblies should not exceed
16
17 s,,l,max,, = 0,75 d (1 + cot α)
18
19 The transverse spacing of the legs in a series of shear links should not exceed s,,t,max,,:
