About this detail

Member B with t1 wall thickness connects to a wide-flange or hollow structural section column using a slotted cap plate and a shear plate, secured with erection bolts as required. A three-eighths-inch cap plate is welded to the hollow structural section on three sides on each side of the gusset with five-sixteenths-inch fillet welds, while leaving the k-area unwelded. At the roof condition, a three-quarter-inch cap plate is detailed with specific clearance dimensions. For skewed connections up to sixty degrees, plates are aligned with the hollow structural section unless otherwise noted on plan.
