About this detail

This structural steel column base plate assembly features a steel column welded to a base plate with three-eighths-inch fillet welds, secured by six one-inch diameter anchor rods with a two-foot minimum embedment length. A two-inch diameter maximum grout hole is provided at the contractor's option in the base plate, which sits over one and a half inches of non-shrink grout. Stiffener plates, matching the thickness of the column web, are welded where specified. The finished column end and base plate are fabricated per AISC standards, with anchor rods tightened snug tight and threads scored to prevent loosening. Plate washers and hole diameters are sized per the AISC Manual Table 14-2, and the contractor must hold the base plate rigidly in place during grouting while coordinating anchor rod placement with concrete reinforcing.
