About this detail

A beam web doubler plate installation at midspan incorporates a gusset plate and main stiffener where required. The doubler plate is centered on the gusset plate unless noted otherwise and joined with groove welds per AWS D1.8 clause 4.3. Fillet welds are specified at the edges based on plate thickness, utilizing 5/16-inch welds for thicknesses under 1.25 inches and 7/16-inch welds for thicknesses under 2.0 inches. Doubler plate thickness is applied either to one side of the web or split evenly as half the indicated thickness on both sides of the web.
