A structural steel beam connects to a supporting column using double angles fabricated from L4x3x3/8 structural steel. The connection utilizes six 7/8-inch diameter A325-N high-strength bolts distributed across spaced intervals with 3/4-inch A572-50 plates. Fillet welds of 3/16-inch and 5/16-inch sizes secure the plate and angle assemblies to the column flange and web elements. Section A-A provides plan and elevation views detailing the bolt hole spacings, edge distances, and plate dimensions.
