Abstract:Twenty-four experimental metal-plate wood roof trusses were tested on four truss types with six specimensin each category. The object of the study was to determine the effect of adding wood wedges from scrap cutoff material to the heel joint. The influence of wedges on both the deflection behavior and the strength of the trusses was observed and analyzed. The King-Post truss was significantly influenced by the addition of the wedge. The deflection behavior of the Fink and Howe type trusses was improved, but only by a small amount. The strength of the Fink and Howe trusses was judged to be unaffected by the addition of wedges.
