These non-frame column base plate details illustrate the connection of a wide flange column and a pipe column or hollow structural section tube to a concrete footing or pilaster. The base plates are anchored with anchor bolts detailed with double nuts, hardened washers, and square plate washers embedded at the footing depth. A three-inch minimum non-shrink grout layer sits beneath the base plate, with a specified grout hole on the base plate matching the anchor bolt hole size. Footing reinforcement includes number four ties at six inches on center with a minimum of three ties at the footing. Fillet welds of five-sixteenths inch or AWS minimum size secure the column profiles to their respective base plates.
