Figure 3.10 Shear force diagram (load at 0.5d) - example 2 modified

In this case it would be prudent to check the shear resistance on the unmodified 1/ = 211 kN. The required shear reinforcement should be provided from x = 0 to x = 0.5d

Check area of shear reinforcement required in example 2.

Re-arranging the equation for Vwd gives

Try R12 links @ 175 mm crs. (4 legs), AsJs = 2.58 mm2/mm

Check crushing of compression strut

V = (i-)^cdbw0.9d(1 + coto) For vertical links, cota = 0
