A stressed skin panel is an engineered, prebuilt component consisting of a frame of dimensional lumber, to which top and bottom flanges of plywood or other panel material are structurally glued. Flanges are traditionally made of Douglas fir, but if made of Alberta spruce plywood and oriented strandboard(OSB), could provide new markets for Alberta. Twenty-four stressed skin panels were designed, constructed and tested: 6 with flanges of Douglas-fir plywood, 6 with flanges of Alberta spruce plywood, and 12 with flanges of OSB. Half were tested to verify that established engineering design theories hold for stressed skin panels made with OSB and spruce plywood flanges, and the other half were tested to study the effect of sustained loading (1000 day duration) on stressed skin panels made with OSB and spruce plywood flanges.
