About this detail

A structural steel gusset plate connects to a column and a base plate, with a brace member framing into the gusset via a bolted connection. The gusset plate is supported by a gusset support plate sized one-half inch minimum for plates under two inches thick, and three-quarters inch minimum for plates two inches thick or greater. Five-sixteenths inch fillet welds attach the gusset to the stiffener on three sides top and bottom typically. The work point is located at the top of the base plate with specified approximate dimensions for layout. Reference details are provided for the buckling-restrained brace and gusset layout procedure.
