The Designer can remove the OMF wood nailers and attach cold-formed steel studs or tracks to the steel beam or column directly using screws, powder-actuated fasteners or by welding. Refer to detail 11/SF3 (PDF) (page 63 in the C-SF10 Strong Frame Ordinary Moment Frame catalog) for welding and fastening limitations. If the wood nailers remain on the steel beam of the moment frame, steel straps can be used similar to detail 7/SF3 (PDF) (page 61 in the C-SF10 Strong Frame Ordinary Moment Frame catalog). Note that wood strap values are listed in the C-2009 Wood Construction Connectors catalog and CFS strap values are listed in the C-CFS10 Cold-Formed Steel Construction Connectors catalog. Alternatively a cold-formed steel track can be attached to the wood nailers using Simpson Strong-Tie® SDS wood screws. The Designer is responsible for designing these connections for the appropriate load combinations of the Code.
