About this detail

This drawing outlines standard notes and details for structural steel moment connections. The assembly features a beam framing into a column with a shear tab and full-height column stiffener plates measuring 3/8 inch by 4 inches minimum on each side to match the beam flange width. Shear tab thickness is determined by the beam web thickness plus 1/4 inch unless noted otherwise, with fillet welds applied to both sides for the full height. Bolt sizing, counts, and specific weld criteria are referenced to the non-moment beam connection schedule. Additional notes govern double-row bolt balancing, standard hole usage, and weld backup plates.
