About this detail

An unbraced parapet connects to a steel stud framing system backed by a continuous angle. A structural steel beam supports the floor joist, with a gravity and stiffener clip connection provided by the supplier. A diagonal strong back angle measuring L3x3x5/16 is used at the mid-length, required if the supporting angle exceeds ten feet in spacing. A bent plate measuring 5/16 inch continuous is used when the deck edge is under fourteen inches, and a 3/8 inch continuous bent plate is used when the deck edge is between fourteen and eighteen inches. Full depth stiffeners are provided opposite the beam or joist connection. Glazing connections to the steel stud framing accommodate vertical deflection and horizontal seismic drifts per the general structural notes.
