Vertical Stirrups or Links

Calculate the ultimate design shear forces V d along the beam s span. 

Check the crushing strength VRd.max of the concrete diagonal strut at the section of maximum shear, usually at the face of the beam support. 

For a predominately uniformly distributed load the shear Vsd should be taken at a distance d from the face of the support and the shear reinforcement should continue to the face of the support. 

This value should be marked on the shear force envelope to show the extent of these links. 

Calculate the additional longitudinal tensile force caused by the shear force
