This assembly connects a structural steel beam and a joist girder to a column using a three-eighths inch cap plate. The beam attaches to the column via a typical shear connection as referenced in detail 1/S303. The joist girder rests on a seat assembly consisting of an L6x6x3/8 angle with a one-half inch stiffener plate, as detailed in 3/S302. A three-quarter inch by six inch by three foot four inch strut plate is positioned atop the cap plate. A stabilizer plate is installed on the column web and is specified to remain unwelded to the girder. Five-sixteenth inch fillet welds are used for the primary connection points.
