About this detail

A structural steel connection joins a column web perpendicular to the beam web, incorporating full-height stiffener plates on both sides of the column aligned with the column web. The stiffener plates match the beam flange width and the column flange thickness with a three-eighths-inch minimum. The top plate is sized according to the formula equating to the beam flange thickness plus one-eighth inch by the beam flange width minus three-quarters inch, extending the column cap plate to match the top plate length. Five-sixteenth-inch fillet welds attach plates to each beam, left unwelded over the transverse beam. Additional connections are designated per plans and reference sheets.
