Tensile force N_perm. [kN]

Shear force V_perm. [kN]

A   C8/10 (f_{ck,cube,current} = 10 N/mm²)

B   C12/15 (f_{ck,cube,current} = 15 N/mm²)

C   C16/20 (f_{ck,cube,current} = 20 N/mm²)

D   C20/25 (f_{ck,cube,current} = 25 N/mm²)

E   C25/30 (f_{ck,cube,current} = 30 N/mm²)

The following simplified values may be used:

▪ Permitted load in C8/10 concrete
with f_{ck,cube,current} ≥ 10 N/mm²:
F_perm. = 11.1 kN (R_d = 16.65 kN)

▪ Permitted load in C20/25 concrete
with f_{ck,cube,current} ≥ 25 N/mm²:
F_perm. = 17.6 kN (R_d = 26.4 kN)

If the boundary conditions differ from those stated above, the approval Z-21.8-2033 must be used!
