About this detail

A stair stringer notches around an HSS member and includes an L2x2x3/16 by 0'-5" stringer bearing shoe. A continuous deck bearing angle (L5x3x1/4) supports the concrete over metal floor deck. A quarter-inch stiffener plate is welded to the supporting steel beam with three-sixteenth-inch welds on three sides. Fillet welds of quarter-inch and three-sixteenth-inch sizes secure the stringer, bearing shoe, and channel and angle components to the HSS. The stringer is spliced at the landing beam and field welded together with a square butt weld on both the flange and the web.
