Braced Frame Connection Gusset Plate Welded Connection

About this detail

A buckling-restrained braced frame connection occurs at a steel column and beam intersection. A gusset plate connects to the centerline of the buckling-restrained brace per the supplier specifications, with welds designed to develop the yield capacity of the gusset and beam web. Stiffener plates are welded top and bottom on each side, with a thickness matching the beam flange thickness plus one-quarter inch. The weld size D for the stiffener plates is calculated as five-eighths times the plate thickness, with a demand critical complete joint penetration weld permitted as an alternative. A web doubler plate is included as required by the brace supplier, and continuity plate clips are detailed at the beam flanges.
