About this detail

A structural steel column frames into a thick base plate anchored to a reinforced concrete footing with twelve one-and-three-quarter-inch diameter high-strength anchor bolts. Gusset plates connect buckling-restrained braces to the column and base plate assembly, utilizing welded connections and shear tabs sized per the manufacturer. Stiffener plates matching the column flange thickness are welded to the base plate with complete-joint-penetration welds. A two-and-a-half-inch maximum non-shrink grout layer sits beneath the base plate, alongside a two-and-a-quarter by six-inch shear lug and one-inch asphalt board on each side of the gusset.
