About this detail

A typical braced frame connection at a column flange features a gusset plate and buckling-restrained brace welded to the framing members. A web doubler plate is located on each side of the column web, with plate thickness matching the beam flange thickness plus one-quarter inch as specified. Stiffener plates are welded to develop the full gusset capacity, utilizing either fillet welds sized per the plate thickness or demand-critical complete joint penetration welds at the contractor's option. A one-inch radius clip is provided on the stiffener plates, which may be reduced in width to match the incoming beam flange if no other connections occur at that location. The beam connects to the gusset and column centerline with reactions detailed per the braced frame elevations.
