About this detail

A structural steel moment connection occurs between steel beams of differing depths framing into opposite column flanges. The assembly incorporates top and bottom flange plates, designated TF1 and TF2, with continuity plates installed inside the column web matching the larger of the two flange thicknesses. Shear transfer is handled by a bolted single-plate shear tab welded to the column flange, with the shear tab thickness specified as the beam web thickness plus one-quarter inch. A second row of bolts is included as required per structural plans, maintaining a three-inch minimum typical spacing. Sloped bottom plates are detailed for conditions with less than three inches of slope, and continuity plates are welded to the top and bottom flanges typically unless otherwise noted.
