A structural steel column base plate connection plan is detailed with grade 50 material and specific anchor rod patterns. Square plate washers with standard holes are welded around the anchor nuts per AISC recommendations. The column web features D1.8-DCW welds with five-sixteenth inch fillets, while the flanges utilize D1.8-DCW complete joint penetration welds. Two-inch diameter grout holes are positioned within the base plate layout along the column centerlines. Anchor rod nuts are specified to be tightened only after the plate washer welds are complete.
