Members not requiring design shear reinforcement: the values of CRd,c, vmin and k1

Eurocode 2 part 1-1: Design of concrete structures   6.2.2 (1)

The design value for the shear resistance VRd,c is given by:

VRd,c = [CRd,c k (100 ρl fck)1/3 + k1 σcp] bw d (6.2a)

with a minimum of

VRd,c = (vmin + k1 σcp) bw d (6.2b)


The recommended value for CRd,c is 0,18/γC, that for vmin is given by Expression (6.3N) and that for k1 is 0,15.

vmin = 0,035 k3/2 fck1/2 (6.3N)
