About this detail

A rigid steel moment connection occurs between a frame beam and a wide-flange frame column. Top and bottom continuity plates match the thickness of the beam flange with a three-quarter-inch minimum and align flush with the column flanges. Complete joint penetration welds secure the continuity plates to the column flanges, leaving the backing in place with an additional five-sixteenth-inch fillet weld underneath. A double plate is provided on the exterior column face where required by the buckling-restrained brace manufacturer. The beam web connects using a bolted shear tab, and weld tabs are omitted adjacent to the column web and flange juncture per AISC 358-16.
