About this detail

A roof joist frames perpendicularly into a perimeter steel beam and balloon-framed cold-formed steel stud wall assembly. The roof assembly comprises steel roof decking over roofing per architectural drawings, supported by a steel joist with a sloped profile resting on a steel beam. A continuous L5x5x5/16 angle header runs along the edge, detailed with standard fillet welds. The vertical metal stud wall is tied to the edge angle using Simpson SCB clips fastened with two number ten screws at each stud. A five-inch wide rectangular hollow structural section blocking, sized to match the seat depth with a three-sixteenths inch minimum wall thickness, provides intermediate support. Additional framing includes a header below and provisions for an architectural window head condition.
