About this detail

Cold-formed steel joists bear beneath metal decking and are tied together using flat strap bridging spaced at forty-eight inches on center or one-half inch deep resilient channels fastened with one number ten screw to each joist and three number ten screws to blocking. L-angles measuring one and one-half by one and one-half by fifty-four mil by five inches long connect with three number ten screws to each leg. Solid blocking of forty-three mil minimum is installed at each end bay of the flat strap bridging run at eight feet on center maximum, and at resilient channel runs spaced at four feet on center maximum. Rim tracks attach to top tracks per metal deck edge attachment plans, utilizing joist sections matching rim track size and thickness fastened with eight number twelve screws to each rim track. Additional bays of blocking and resilient channel are required for fire assemblies per the architect, and rim tracks must not be spliced within forty-eight inches of the top track.
