About this detail

A structural steel column base plate is anchored to a concrete support. The assembly consists of a structural steel column welded to a steel base plate with five-sixteenth-inch fillet welds, supported by four three-quarter-inch diameter anchor rods with a one-foot minimum embedment. A two-inch maximum grout hole is provided at the contractor's option, and non-shrink grout fills the one-and-a-half-inch space beneath the base plate. Anchor rods are tightened snug tight with threads scored to prevent loosening, and base plate hole diameters and plate washers are sized per the AISC Manual. Specific anchor rod gauges are designated for W10, W12, and W14 column profiles.
