About this detail

A stair stringer connects to a three-sixteenths inch bent plate nosing between stringers, supported by six-inch wide cold-formed steel studs framing down to a wide-flange beam. The stair framing assembly ties into the roof deck with a five-inch track connection per plan notes. A closure plate connects via a one-half inch diameter weld at twelve inches on center. The structural steel wide-flange beam supports the cold-formed steel stud wall framing above at the roof level.
