R

314 mm2

This is a point intermediate between the section at dfrom support and the point at which shear reinforcement is no longer required.

Since VSd > 1/ shear reinforcement is required

Re-arranging EC2 Eqn 4.23

Try R12 links @ 250 mm crs. (4 legs) = 1.81 mm2/mm Check maximum spacing of links A

For vertical links sina = 1 Hence
