Reinforcing against Rib Shearing Failure in Composite Edge Beams

Brittle rib shearing failure comprises horizontal splits that form in the concrete between the tops of the steel sheeting ribs in pans where there are shear connectors, while the failure surface locally avoids the studs by passing over their heads. It has been reported in the literature to have often occurred in push-out and beam tests. It is now mandatory in Australian Standard AS 2327, Part 1 to reinforce composite edge beams against rib shearing failure. A patented reinforcing component has been developed for this purpose.
