About this detail

A structural steel moment connection between a frame beam and a frame column includes top and bottom continuity plates and a bolted web connection. The continuity plates are sized to match the beam flange thickness with a three-quarter-inch minimum and are welded to the column flanges using complete-joint-penetration welds with backing left in place and a five-sixteenth-inch fillet weld added underneath. Where beams occur on both sides, the thicker beam flange governs the sizing of the continuity plate thickness. Double plates are located on the exterior column face where required per the buckling-restrained braced frame manufacturer. Complete-joint-penetration welds are also specified at the beam web, and weld tabs are omitted adjacent to the column web-flange juncture in accordance with AISC 358-16 section 3.6.
