About this detail

A steel stair assembly features HSS14x6 stringers connected to HSS8x6 and HSS10x6 members, supported by HSS4x4 posts at the first landing. Full penetration shop welds are specified at the stringer and landing frame junctions, as indicated by typical callouts. The structural frame is designed to accommodate twenty-one pounds per square foot of superimposed dead load, with concrete and pans at treads and landings provided by the stair manufacturer. Grid alignments and reference elevations establish the vertical and horizontal placement relative to the architectural drawings.
