About this detail

A structural steel frame column sits atop a base plate anchored to a concrete footing via anchor bolts with square plate washers and embedment ties. A gusset plate connects the buckling-restrained brace to the column web and base plate, featuring a 1-1/2 inch by 1-1/2 inch snip or radius. A three-inch non-shrink grout layer is detailed beneath the base plate, with a column blockout increased as required to allow clearance for the gusset plate. The column web is welded to the base plate with a 5/8 inch fillet weld, and the column flange to base plate connection includes a 5/8 inch weld sized as flange thickness divided by two plus 1/8 inch. Anchor bolt diameters, lengths, and embedments are sized per schedule.
