About this detail

Two typical structural conditions comprise an HSS beam to HSS column connection and a reinforced CMU wall on a concrete footing. The steel connection features a one-quarter-inch thick cap plate field-welded to the top of the HSS column and beam with an eighth-inch perimeter fillet weld, with similar conditions at beams on both sides. The masonry detail shows an eight-inch solid-grouted concrete masonry unit wall with number five vertical reinforcing bars at twenty-four inches on center with forty-six-inch lap splices, supported by a concrete footing with number five continuous bars and number five bars at twelve inches on center. The footing includes a thickened edge at the contractor's option and a water stop per architectural requirements. Additional notes specify providing one vertical bar at wall ends, one horizontal bar at the top of the wall, and prohibiting openings without engineer approval.
