Design punching shear resistance of a slab without shear reinforcement: the values of CRd,c, vmin and k1
Eurocode 2 part 1-1: Design of concrete structures 6.4.4 (1)
The design punching shear resistance vRd,c [MPa] may be calculated as follows:
|vRd,c = CRd,c k (100 ρl fck)1/3 + k1 σcp ≥ (vmin + k1 σcp)||(6.47)|
In this calculation of the design punching shear resistance, the recommended value for CRd,c is 0,18/γC, that for vmin is given by Expression (6.3N) and that for k1 is 0,1.
|vmin = 0,035 k3/2 fck1/2||(6.3N)|
