About this detail

Steel web doubler plates are applied to beam and column webs for heavy-load structural connections. The assembly incorporates web doubler plates attached via groove welds per AWS D1.8 Clause 4.3, with doubler thickness applied to one side of the web or split evenly on both sides. Gusset plates feature stiffeners on both sides sized per the connection schedule, utilizing 5/16 inch fillet welds for thicknesses under 1.25 inches and 7/16 inch fillet welds for thicknesses under 2.0 inches, unless noted otherwise. Shear tabs and stiffener plates connect to beam webs using complete joint penetration groove welds or specific fillet weld sizes. Stiffener plates extend past the column flange with specified edge clearances and minimum weld sizes.
