About this detail

An HSS 6x6x1/4 knee brace connects back to cold-formed steel stud framing and up to a timber beam. The top of the brace features a three-eighths-inch steel plate with timber infill, secured to the timber beam above using a three-eighths-inch by four-inch knife plate with a three-quarter-inch diameter through bolt, recessed and plugged. Section B-B details this knife plate connection centered on the timber beam with a one-inch-diameter threaded rod and a three-sixteenths weld. Section A-A details the lower connection at the cold-formed steel studs, utilizing cold-formed steel blocking matching the stud gauge, six self-tapping screws of minimum number twelve size on each side, plywood backing behind waterproofing, and solid blocking behind the exterior finish.
