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 vEd is less than or equal to k⋅fcd no extra reinforcement above that for flexure is required.
Recommendation
The recommended value of k for the calculation of the lower limit of longitudinal shear stress is 0,4.
