About this detail

A wind girt and fire separation assembly ties into structural steel framing and metal roof decking. Six-inch eighteen-gauge cold-formed steel studs (600S162-43) spaced at sixteen inches on center with a continuous sixteen-gauge top track (600T125-54) run vertically beneath structural steel beams sized per plan. Gypsum board is installed on the stud wall as specified by architectural drawings. A one-quarter-inch steel bent plate featuring a five-inch vertical leg connects the assembly, with the bent plate leg extending one inch beyond the centerline of the beam as required. Number twelve self-tapping screws at each stud fasten through zero-point-two-two-eight-inch by three-inch vertical slots in the plate, while number twelve self-tapping screws spaced at twelve inches on center are staggered into horizontal slots parallel with the beam. A continuous sixteen-gauge bent plate with three-inch bends caps the top of the wall between the adjacent metal roof deck sections.
