About this detail

A structural steel column base plate rests on a reinforced concrete footing with non-shrink grout and multiple anchor bolts. A gusset plate connects a buckling-restrained brace to the column base, with stiffener plates welded to the column flanges and base plate using complete joint penetration and fillet welds. A 2-inch by 6-inch shear lug is embedded in the concrete footing beneath the base plate, surrounded by a 1-inch clearance for grout. The concrete footing includes top and bottom reinforcing mats with standard 90-degree hooks, while asphalt board is placed on each side of the gusset.
