This assembly consists of a wide-flange column welded to a one-inch thick ASTM A572 Grade 50 steel base plate. The connection is secured by eight one-inch diameter ASTM F1554 Grade 105 fully threaded anchor bolts, each featuring a two-inch diameter hole in the base plate and a square plate washer with a standard hole. The column is attached to the base plate using two distinct weld types, W1 and W2, both specified as double-sided continuous welds. The anchor bolt layout is defined by dimensions B and L, with specific edge distances E and D4 provided for typical installation.
