About this detail

Loose-shipped collar assemblies are installed on single and double tube buckling-restrained braces connected to structural steel gusset plates and columns. The collar assembly is positioned against the edge of the gusset plate after the brace is fully welded, utilizing field-applied fillet welds sized at five-sixteenths of an inch. Field notes instruct the erector to remove the temporary rebar stop prior to sliding the collar into position. Optional weld placements are permitted on either the near or far side of the gusset plate, and on the top or bottom side of the core plate, at the erector's option.
