SHEAR
The design shear resistance of a single anchor is the lower
of
VRd,c : concrete edge resistance
VRd,s : steel resistance
VRd,c : Concrete edge design resistance
The lowest concrete edge resistance must be calculated. All near
edges must be checked, (not only the edge in the direction of
shear). The direction of shear is accounted for by the factor f
,V.
