Transverse reinforcement at lapped splices should be provided as for a beam section. Since 0 < 16 mm, nominal shear links provide adequate transverse 5.2.4.1.2(1)

This detailing prohibits the easy use of prefabricated rib cages because of the intersection of the bottom reinforcement with the supporting beam cage. It is suggested that providing suitably lapped continuity bars through the support should obviate the need to continue the main steel into the support.

The arrangement of the reinforcement within the section including the anchorage of the links is shown in Figure 4.13.
