About this detail

A buckling-restrained braced frame beam stub connects to a steel column weak axis using a continuous gusset plate passing through the beam stub. The stub flange plate thickness matches or exceeds the beam flange thickness, and its width equals the column depth minus two times the column flange thickness within a one-sixteenth-inch tolerance, featuring one-inch corner clips at each side of the column web. Fillet welds of five-sixteenth-inch size secure the stub flange plates to the column flange and the gusset plate, while one-half times the plate thickness fillet welds or D1.8-DCW welds attach the stub flange plates to the column web. A complete joint penetration groove weld attaches the gusset plate directly to the column. Stiffener plates and the buckling-restrained brace connect per the manufacturer schedule, with concrete on steel deck omitted for clarity.
