Shear stress for a section of plain concrete member: the value of k

Eurocode 2 part 1-1: Design of concrete structures   12.6.3 (2)

In plain concrete members, for a section subject to a shear force VEd and a normal force NEd acting over a compressive area Acc, the absolute value of the design shear stress τcp should be taken as:

τcp = k VEd / Acc (12.4)

and the following should be checked: τcp ≤ fcvd where fcvd is the concrete design strength in shear and compression.


The recommended value of k is 1,5.
