About this detail

An HSS column is supported by a wide flange beam, featuring a three-quarter-inch base plate welded to the column base and secured with four seven-eighth-inch diameter A325 bolts. A leveling shim plate up to one-half-inch maximum is provided as required beneath the base plate. The wide flange beam includes full-height three-eighth-inch stiffener plates on each side unless otherwise noted, with a one-quarter-inch stiffener plate noted as acceptable for W16 or shallower beams with flanges five-eighths-inch thick or thinner. Fillet welds are specified at three-sixteenths-inch for stiffeners and one-quarter to five-sixteenths-inch for webs or flanges over three-quarters-inch thick, with standard 'k' by 'k' chamfers at the beam web-to-flange junctions. A note indicates that where beams frame into the stiffener plate, thicker stiffener plates and welds may be required per detail 2/S5.01.
