About this detail

A steel column is supported by an incoming beam and a three-half-inch plate. A Level 2 framing connection features a three-quarter-inch side plate, one-quarter-by-four-inch stiffener plates at eighteen inches on center, and a bent three-eighths-inch plate with quarter-inch welds across flats, set back one-half inch to coordinate with curtain wall attachments. Notes require a three-foot continuous weld at each end of the beam, allow holding the side plate back six inches for connection access, and mandate coordinating stiffener plates with curtain wall embed locations within six inches on center. An eight-inch concrete curb sits on a steel deck reinforced with two continuous number four bars, additional number four bars at eighteen inches on center, and an HSS6x6 hollow structural section anchored with three-quarter-inch diameter studs welded to plates at three feet on center with four inches of embedment.
