A wide-flange steel beam supports a concrete slab and metal deck assembly with a depression parallel to the beam. A twelve-gauge bent plate forms the edge of the depression, welded with a one-eighth-inch fillet weld at twelve-inch intervals. Two continuous number four reinforcing bars with standard ninety-degree hooks provide development across the depression edge, supplemented by typical slab reinforcement. The maximum depression depth is four inches, with slab thickness dimensions governed by structural plan requirements.
