About this detail

An incoming steel beam connects to a vertical column via a welded moment connection and a bolted shear tab. The beam flanges feature top and bottom flange extension plates with thicknesses matching the beam flange. Horizontal stiffener plates inside the column match the incoming beam flange thickness plus one-quarter inch, welded with complete joint penetration welds at the top and bottom flanges. Two seven-eighths inch diameter A325 bolts secure the beam web through a shear tab. Quarter-inch fillet welds are specified at the vertical and horizontal stiffeners.
