About this detail

A wide-flange beam frames into a column with a bolted connection and an intersecting HSS brace secured by a gusset plate. The cap plate thickness equals the beam flange thickness plus one-quarter inch, sized to match either the column width or beam width, whichever is greater. A five-sixteenths inch fillet weld secures the cap plate to the column. Bolt quantities are determined by the structural schedule, with specific provisions for added bolts spaced at three inches on center when dimensions exceed six inches. The gusset plate is welded with specified weld sizes and orientations, including reinforcement as detailed in the structural schedule.
