About this detail

An unbraced parapet framing assembly connects to a structural steel beam and steel joist parallel to the exterior. A continuous L6x4x3/8 angle supports the parapet base, with L4x4x5/16 angles spaced at a maximum of seven feet on center. An L3x3x5/16 strong back is provided at mid-length when the L4x4x5/16 angle exceeds ten feet. The steel joist or beam bears on framing with cope angles as required, taking a wind adload of plus or minus five kips. A full-depth stiffener is welded to the steel beam with a quarter-inch fillet weld. A metal roof deck spans to the framing, and a steel stud system accommodates vertical deflection and horizontal seismic drifts.
