A steel tube stair stringer frames into a structural steel beam supporting a concrete slab over a steel deck. The stair stringer features a coped end at the bearing location, capped with a one-quarter-inch thick steel closure plate welded with a three-sixteenth-inch typical fillet weld. The concrete slab and metal deck are blocked out at the stair stringer bearing location, referencing the architectural drawings for stair tread details. Complete joint penetration welds are specified typically at the connection joints.
