About this detail

These structural details illustrate various composite metal deck bearing conditions and slab step configurations supported by wide-flange steel beams. The assemblies incorporate angles such as L4x3x1/4, L5x3x1/4, L3x3x1/4, and L3x3x1/2, bent plates of 5/16 inch and 1/4 inch thickness, and continuous plates welded with three-sixteenths inch fillet welds at eight inches on center. Headed studs sized at three-quarters of an inch diameter by four inches long are spaced at twelve inches on center and aligned with deep deck flutes. Deck conditions specify crimping to lie flat for welding, with maximum deck slopes and discontinuities detailed per structural notes.
