About this detail

A cold-formed steel parallel joist frames into a wall stud assembly with an XXXS200-54 ledger track. The ledger track is fastened using number 10 screws top and bottom to the joist, and number 10 screws at eight inches on center to the blocking, with a minimum of two number 10 screws to each stud. Blocking is spaced at forty-eight inches on center, matching the joist size and providing a two-inch minimum web extension with three number eight screws to the joist and rim track typically. An MTS12 strap is installed at forty-eight inches on center, requiring a gouged gypsum board finish at the strap location. Diaphragm boundary fastening secures the roof sheathing to the blocking and ledger, while shearwall edge fastening ties the exterior wall sheathing.
