About this detail

A carried steel column sits atop a three-quarter-inch thick cap plate fastened to a supporting steel beam with four three-quarter-inch diameter A325 bolts. Three-eighth-inch thick stiffener plates align with the column flanges on each side of the web, welded with three-sixteenth-inch fillet welds on three sides typical. The beam web features a sleeved penetration located within the middle one-third of the span, flanked by reinforcing plates matching the web thickness on each side. Welds sizing follows AISC specification section J2 and project connection schedules, with pipe sleeves detailed where dimensions are three inches or less.
