About this detail

A steel girt connects to a structural steel column flange using a bolted angle or direct flange connection with slotted holes to accommodate movement. At the hollow structural section girt, an L6x6x1/2 angle sized to one-half the column flange width minus three-quarters of an inch is bolted to the column with two seven-eighths-inch diameter bolts centered on the angle with three-inch slotted holes through the angle. Washers are used to shim girts as required. Web stiffeners of one-half-inch plate are welded to each side of the column centered on the girt, with a one-quarter-inch fillet weld on three sides typically. At the wide flange girt, two seven-eighths-inch diameter bolts with three-inch slotted holes pass through the girt flange directly to the column flange, supplemented by one-half-inch web stiffeners on each side of the column. Section views show the layout of the bolted connections and three-eighths-inch angle stiffeners with specified minimum edge distances.
