About this detail

An unbraced roof parapet and exterior wall condition features steel joists running perpendicular to the exterior framing. A steel beam supports the roof deck, tying into a continuous bent plate measuring five-sixteenths of an inch thick when the deck edge is under fourteen inches, or three-eighths of an inch thick when the deck edge is between fourteen and eighteen inches. A gravity and stiffener clip connection by the supplier secures the steel beam to the exterior steel stud framing, designed to accommodate vertical deflection and horizontal seismic drifts. Additional support is provided by angle sections including L4x4x5/16 at a maximum seven-foot spacing and continuous L6x4x3/8 angles with complete joint penetration welds at splice locations. A strong back angle L3x3x5/16 is included at mid length and is required if the L4x4x5/16 angle exceeds ten feet in length.
