About this detail

A buckling restrained brace connects to a steel column flange at a floor or roof level. The assembly incorporates a gusset plate and connection designed and supplied by the buckling restrained brace supplier, with the gusset plate and brace steel core designated as a protected zone. Frame beams frame into the steel column using shear plates equipped with three seven-eighths inch diameter erection bolts, where plate thickness equals beam web thickness plus one-eighth inch. Stiffener plates are provided near side and far side, with a thickness equal to the greater beam flange thickness plus one-eighth inch. Complete joint penetration welds are specified for the top and bottom beam flanges, alongside five-sixteenths inch typical fillet welds and web stiffeners as required by the brace supplier. Foam blockouts are provided around the buckling restrained brace lugs and casings encased in concrete, with one inch of foam on each side perpendicular to the brace and a three-inch foam blockout at the end of the casing.
