About this detail

A built-up steel stair stringer frames into a supporting steel beam with a one-half-inch plus or minus gap at the top landing. The assembly utilizes full-depth stiffener plates welded to the stair stringer and to the steel beam web, supplemented by a structural steel angle bearing support centered on the stringer. A concrete over metal deck slab bears on the structural framing above. Stair geometry is coordinated per architectural drawings.
