About this detail

Cold-formed steel stud wall bridging and splice options comprise double flat strap with blocking, screw-attached bridging channel with angle, and weld-attached bridging channel with angle. Option A features 1-1/2 inch by 43 mil taut horizontal flat straps at 48 inches on center maximum with S162-43 blocking secured by a minimum of four number 10 screws on each side, utilizing number 10 screws at each strap-to-stud intersection. Option B and Option C incorporate 54 mil by 1-1/2 inch bridging channels through standard punchouts with L 1-1/2 by 1-1/2 by stud depth minus 1/2 inch by 54 mil angles fastened with two number 10 screws on each leg, where Option C permits a welded connection requiring a 43 mil minimum stud thickness. Additional criteria require bridging options A, B, or C for stud depths six inches or less, and Option A exclusively for stud depths greater than six inches. Flat straps may be omitted on the exterior side of shear walls with sheet steel or SureBoard sheathing while blocking remains mandatory, and resilient channels may be substituted for flat straps when installed per this detail.
