About this detail

Buckling restrained braces connect to gusset plates welded to a structural column and base plate, anchored to a concrete foundation. A five-sixteenths inch fillet weld secures the gusset to the stiffener plate on three sides top and bottom. A one-half inch minimum gusset support plate and gusset edge stiffener may be built as a single plate where both are required, with the more stringent requirement governing. Concrete blockouts surround the base within the slab on grade, and a work point is established at the top of the base plate.
