About this detail

An angle brace connection is framed between steel beams supporting a concrete fill over metal deck. The assembly features an angle brace made of an L6x6x1/2 angle with four 3/4-inch diameter Nelson studs located at the troughs of the steel deck. Each end of the brace connects via a 3/8-inch plate secured with two 7/8-inch diameter A325N bolts unless noted otherwise. At frame beams, a full height stiffener plate is used, with a width as required for two bolts and a 3/16-inch weld on two sides. The 3/8-inch plate may be field welded to the beams at the contractor's option, requiring a ten-inch minimum total weld length. Per the drawing notes, unless noted otherwise on plans, the angle brace size varies by length: an L4x4x3/8 angle is used for lengths under six feet, and an L6x6x3/8 angle is used for lengths between six and ten feet.
