About this detail

A built-up steel stair stringer connects to a supporting steel beam with a one-half inch gap maintained between components. A bearing support angle measures four by four by three-eighths inches by twenty inches long centered on the stair stringer and connects to the steel beam web. Full depth stiffener plates of specified thickness attach on each side of the stair stringer and to the steel beam web with welded connections. Concrete over metal deck finishes the floor assembly above the supporting beam. The stair stringer aligns centered on the support beam connection.
