About this detail

Lateral framing connection at a stair tower floor, comprising a concrete slab over metal floor deck supported by composite steel beams with shear stud anchors. At the hollow structural section column, a three-eighths-inch cap plate is welded where the column ends using a three-eighths-inch weld, with five-sixteenths-inch fillet welds securing framing members. A bent plate is notched around the steel stair tower column, supported by a continuous angle welded to the column with a five-sixteenths-inch fillet weld. Fillet groove and flare bevel welds are interchangeable per member geometry, with flare bevel welds replaced by five-sixteenths-inch effective fillet welds where geometry permits.
