About this detail

A structural steel beam-column connection features a buckling-restrained brace framing into the intersection. A gusset plate connects to the beam and column, with welds designed to develop the yield capacity of the gusset and beam web. Top and bottom plates match the beam flange thickness plus one-quarter inch, and demand-critical complete joint penetration welds are specified. A web doubler plate is included as required by the brace supplier, and continuity plates are clipped per standard details. Fillet weld sizes are determined by the formula D equals five-eighths times the plate thickness, with a demand-critical complete joint penetration weld permitted as an option.
