Steel floor deck bearing and welding details supported by structural steel beams with concrete fill. Deck is oriented perpendicular to beams with intermediate bearings using weld A, butt joints, end bearings, direction changes with eighteen gauge end closures, and deck side lap welds requiring crimping before welding and pressing deck down to engage. Parallel deck to beam details include deck centered preferred, deck offset, lap joints with continuous fourteen gauge plates, deck split, and deck edge configurations utilizing six-inch stud diameter minimums and weld B or weld C designations.
