About this detail

A wide flange beam frames into the web of a wide flange column with complete joint penetration welds at the top and bottom flanges. Horizontal stiffener plates welded to the column web match or exceed the thickness of the thickest beam flange and are specified as minimum half-inch plates in ASTM A572 Grade 50 steel. A bolted shear plate connects the beam web, utilizing a vertical row of four bolts with standard edge distances and three-inch spacing on center. Fillet welds secure the shear plate on three sides typically. Additional shear plate thickness, bolt size, and welding criteria are referenced to sheet A/S5.22.
