About this detail

A metal deck bears parallel to the edge of a concrete slab on a structural steel beam requiring a minimum deck bearing of 1 1/2 inches. An edge closure bent plate is welded to the deck and beam flange with 1/8-inch fillet welds, with plate gauge sized according to dimension L up to and including 12 inches. Top reinforcing steel consists of #4 bars measuring 2 feet 6 inches long spaced at 18 inches on center over 10, 12, and 14 gauge plates. A lap closure of 2 1/2 inches minimum is provided at the deck lap. At guiderail conditions, a 1/2-inch bent plate is provided per architectural drawings, and the height of the closure must be coordinated with the architectural topping slab typical.
