About this detail

A structural plan detail for a steel column base plate connection shows sizing rules, fillet weld requirements, and clearance dimensions. A lookup table correlates base plate thicknesses ranging from three-eighths of an inch to seven-eighths of an inch and greater with corresponding fillet weld sizes of three-sixteenths, one-quarter, and five-sixteenths of an inch. Fillet welds are specified on either side of the column flange, with dimension t defined as the distance between the k-regions per AISC standards. An optional one-inch diameter grout hole is located centrally, and a general note mandates that welding is left out of the column k-region.
