# Shear between web and flanges: the value of `k` for the lower limit of longitudinal shear stress

## Eurocode 2 part 1-1: Design of concrete structures 6.2.4 (6)

If the longitudinal shear stress `v _{Ed}` is less than or equal to

`k`⋅

`f`no extra reinforcement above that for flexure is required.

_{cd}## Recommendation

The recommended value of `k` for the calculation of the lower limit of longitudinal shear stress is 0,4.
