About this detail

A structural steel beam connects to a column flange utilizing a typical shear connection and a top-and-bottom plate connection with complete joint penetration welds. Five-eighths inch thick stiffener plates are provided on each side of the column web, aligned with the beam flanges. A three-eighths inch doubler plate fits between the stiffeners and column flanges, welded per standard details. Additional plate attachments and welded connections are specified with typical fillet and complete joint penetration weld sizes. A plate element sits atop the beam flange, and grating is omitted for clarity.
