About this detail

Structural steel moment connections between a wide-flange beam and a column incorporate both a bolted connection configuration with slip-critical bolts and a welded connection option. Top and bottom plates sized to match the beam flange thickness plus one-quarter inch connect the beam flange, with complete joint penetration welds specified at the column face. Continuity plates and clipped flange details at the column web reinforce the connection zone under heavy moment loads. Additional callouts specify minimum clearances, edge distances, and special handling when the incoming beam flange exceeds the column flange width.
