A structural detail presents a buckling-restrained braced frame column base connection anchored to a concrete foundation. A wide flange W8 column rests on a 1-1/4 inch thick embedded base plate with standard anchor bolt holes and two 1-1/2 inch grout holes, set over a 2 inch non-shrink grout layer. A knife plate measuring 1x7 inches is slotted through the centerline of the HSS6x4 structural steel brace and welded with 1/4 inch fillet welds. Additional 1/2x7 inch plates with four 7/8 inch diameter high-strength bolts connect the assembly, while 3/4 inch diameter by 4 inch headed studs are spaced at 18 inches on center on each side of the hollow structural section. Five-sixteenth inch fillet welds are applied around the base connection components as specified.
