About this detail

Structural reinforcement methods for penetrations in composite steel deck and concrete floor assemblies. The left assembly shows openings cut through no more than three adjacent webs for six-inch and eight-inch module decks or two adjacent webs for twelve-inch module decks, framed with typical L1-3/4"x1-3/4"x1/4" angles placed on top of the formlock deck and extending three webs past the opening. The right assembly displays framing for larger rectangular or square holes utilizing 1-1/2"x3"x1/8" steel tubes positioned on top of the deck with supplementary rebar added to the corners of the openings above the tubes. Supporting beams run below the webs of the steel decking to maintain structural integrity across the cut floor sections.
