This structural connection features a buckling-restrained brace (BRB) attached via a five-eighth-inch gusset plate welded to a W18x55 beam and a structural steel column per schedule. The beam connects to the column through a beam splice plate that is half-inch Grade 50 steel secured with two rows of A325-SC bolts. Three-eighth-inch transverse stiffener plates are welded to the top and near side, far side flanges with five-sixteenth-inch fillet welds. The gusset plate is welded to the beam and column flange using five-sixteenth-inch fillet welds with specified lengths. A complete joint penetration weld with backing bar connects the top and bottom flanges.
