A structural steel connection detail features a roof framing assembly with an HSS8x3x3/16 member and an HSS8x8x1/2 backing post at eight inches on center. The wide-flange beam connects to the column assembly with three-eighths-inch plates welded on each side of the HSS5x5 using three-sixteenths-inch fillet welds on three sides. A one-inch-diameter ASTM A325 high-strength bolt in a longitudinal slotted hole provides a slip connection with a one-inch maximum gap. Double-angle braces sized at 2L3x3x1/4 attach at eight inches on center maximum, secured with shotpins at four inches on center to the roof deck. Additional connection sub-details incorporate angles like L8x6x1/2 with two three-quarters-inch high-strength bolts and notched vertical legs to maintain continuity over the supporting beam.
