About this detail

A structural steel column base plate connection utilizes a base plate welded to a hollow structural section column. The assembly is anchored with four three-quarter-inch diameter anchor rods featuring a minimum one-foot embedment into the concrete foundation. A one-and-a-half-inch layer of non-shrink grout is specified beneath the base plate, with finished column end and base plate per AISC standards. A five-sixteenths fillet weld connects the column to the base plate, supplemented by a partial penetration groove weld where the plate edge is less than nine-sixteenths of an inch from the column face. The contractor must hold the base plate rigidly in place while grouting, and tighten anchor rods snug tight while scoring threads to prevent loosening.
