About this detail

An L7x4x3/8 by three-foot-long angle spans horizontally beneath the metal deck, spaced at six feet on center and located halfway between joists. The angle is secured to the existing metal deck using 14-28 self-tapping sheet metal screws at six inches on center, with two screws provided at each end of the angle for a total of eight. A one-foot-two-inch by six-inch by three-eighths-inch plate connects the angle to the existing open-web steel joist using five-sixteenth-inch fillet welds. At locations with decking on each side, the brace may be positioned on either side of the open-web steel joist.
