About this detail

A steel column base plate rests on a supporting structural steel beam with finished column end and base plate per AISC standards. Four three-quarter-inch-diameter A325 slip-critical bolts with oversized holes secure the base plate, accompanied by typical quarter-inch by two-inch by two-inch plate washers. Alternatively, four one-and-a-quarter-inch-diameter A490 slip-critical bolts with oversized holes are used with half-inch by three-inch by three-inch plate washers. Internal stiffener plates match the thickness of the column web above with a three-eighth-inch minimum and the width of the beam flange, fitted to bear and welded with five-sixteenth-inch fillets. The assembly maintains a half-inch maximum clearance above the toe of the fillet, with three-sixteenth-inch fillet welds at the plate washers.
