About this detail

A structural beam to column flange moment connection utilizes top and bottom flange stiffener plates matching the grade and thickness of the largest incoming beam flange. Complete joint penetration welds connect the top and bottom flanges, with a 1/4-inch partial joint penetration weld or optional single cap plate specified at the top of the column. For beams of varying depth, the stiffener plates are skewed as required to align with incoming beam flanges on each side of the column. Additional connection requirements direct the contractor to typical detail types C1 or C2.
