About this detail

A stair stringer connects to a supporting steel floor beam at a slab edge. The assembly features a stair stringer aligning with a concrete fill over a metal floor deck, utilizing stair pans configured to act as pour stops as coordinated with architectural drawings. A one-quarter-inch stiffener plate is welded to the channel with fillet welds sized at one-quarter inch typical on three sides and three inches long. The steel beam web and flanges receive welded connections indicated by three-sixteenth-inch and one-quarter-inch fillet welds. Slab edge requirements are referenced to coordinate with separate detailing.
