About this detail

A buckling-restrained braced frame connection occurs at a foundation, shown for both column flange and column web conditions. The assembly features a brace connecting to a gusset plate, a drag member, and a base plate anchored to a concrete foundation with anchor rods and embedded plates. Welded headed studs are distributed along the embedment, and stiffener plates are provided as required by the manufacturer. Spacer plates match the thickness of the gusset at quarter-points, and fillet welds are specified on near side and far side as noted. At exterior conditions, the bolts of the brace to the gusset connection are specified not to be encased in concrete.
