About this detail

A buckling-restrained brace connects to a steel column and frame beam intersection using a gusset plate and welded connections. The gusset plate and its connection are provided by the buckling-restrained brace supplier, with the protected zone encompassing the gusset plate and brace steel core. Stiffener plates are installed near side and far side on the beam, sized equal to the greater beam flange thickness plus one-eighth inch. If beams are of different depths, the lower stiffener plate slopes from beam flange to beam flange at a maximum slope of one-to-two, or an additional stiffener plate is added. A shear plate with three seven-eighth-inch diameter erection bolts connects the beam web, with plate thickness equal to the beam web thickness plus one-eighth inch. Complete joint penetration welds are specified at the top flange and top and bottom flanges of the framing members, supplemented by five-sixteenth-inch fillet welds and weld access holes as indicated.
