Sw

Link reinforcement required for shear A

Note that Asw for shear relates to the total shear link legs. Assuming single links, total area for one leg

SW 2

Using T12 links

0.67s = 113 mm2 s = 168 mm, say 160 mm Maximum link spacing for shear

Eqn 5.18

Therefore s = 300 mm max

For cracking

Pwbwd Table 4.13

Therefore s = 300 mm max

For torsion

max g uk = 2[(1500 - 107) + (250 - 107)] = 3072 mm Therefore
