About this detail

Steel framing connections occur at edge beams supporting concrete slabs on metal deck or roof decks. The assembly incorporates a connection plate on the incoming beam web, combined with stiffener plates aligned with the beam flanges and welded on three sides. Where a concrete slab does not exist at the edge beam, the connection plate extends to the full depth of the member. Complete joint penetration welds occur at the top and bottom flanges, supplemented by fillet welds as indicated on the drawing notes. Contractors have the option to extend the connection plate to the bottom flange and weld it directly in lieu of adding a separate stiffener plate.
