The equation for V can be modified to give a range of values corresponding to the distance from the support.

As in Section 3.3.2.1

Values of design shear resistance, V , and design shear resistance to be provided by shear reinforcement, V , are given in Tables 3.6 and 3.7.

Therefore maximum shear reinforcement is required when VRd1 = 328 kN, i.e., when x = 1.35 m

This should be provided from x = 0 to x = 2.25 m (0 < x < 2.5d) Check area of shear reinforcement required.

Re-arranging the equation for Vwd Eqn 4.23

— = - = - = 3.61 mm /mm s (0.9d)/ywd 0.9 x 900 x 217.4

Try R12 links @ 125 mm crs. (4 legs), AJs = 3.62 mm2/mm Check crushing of compression strut

From example 2, VRd2 = 1782 kN > VSd = 1100 kN OK

Check maximum spacing of links 4.4.2.3

By comparison with example 2, requirements are satisfied OK 5.4.2.2(7)

Use R12 links @ 125 mm crs. (4 legs) for 0 < x < 2.25 m

For the remainder of the beam beyond x = 2.5d (2.25 m) provide minimum reinforcement as example given in Section 3.2.2.
