A structural steel bridge roof cantilever connection is supported by a W14x211 column and a W16x100 beam. A W10x88 tapered beam connects to the column using a 1-inch thick vertical end plate and twelve 1-inch diameter by 4-1/4-inch F1852 bolts, supplemented by a 1-inch by 16-inch vertical end plate and a 1-inch by 6-15/16-inch stiffener plate with a 5/16-inch fillet weld. A 1/2-inch by 17-inch cap plate is welded to the top of the column with a 3/4-inch weld, noting no welding at the K zones. The outer end of the cantilever features an HSS6x4x3/8 hollow structural section beam connected via a 1/2-inch by 5-1/2-inch shear plate and four 3/4-inch by 2-1/4-inch A325N bolts, with a 1-inch by 10-inch flange plate welded underneath with a 5/16-inch partial joint penetration weld. S4S 3x12 wood nailers are secured along the top of the steel framing members.
