Angle braces measuring 3 inches by 3 inches by one-quarter inch are welded to the steel beam at every joist location using three-sixteenth-inch fillet welds, with angle braces welded to the beam after the roof is on. A 6x nailer matching the beam flange width sits between the bar joists, secured with seven-eighth-inch diameter wood screws at 12 inches on center. Steel bar joists frame into the assembly, with spacing detailed on the roof framing plan. The structural steel beam is sized per the roof framing plan and includes a bottom flange weld connection indicated with a one-quarter-inch fillet weld symbol. Brace locations must be coordinated with sprinkler pipes.
