    Abstract

    Wood-plates and dowels are used increasingly as connectors in furniture, wood cases, and cabinet joints. Little information is available, however, for the strength of the wood-plate joint design. This study was designed to obtain background information on bending moment resistance of single wood-plate joints in particleboard and solid lodgepole pine lumber, and to also formulate equations for predicting the bending moment resistance of wood-plate corner joints in particleboard and lodgepole pine lumber. Results indicated that the bending-moment resistance was positively related to the size (surface area) of the wood-plate. The average bending-moment resistance increased from the #0 (smallest) to the #S-6 (largest) plates in both substrates. Wood-plate joints averaged 21 percent higher resistance under compression loading for lodgepole pine than those under tension loading for this substrate. Wood-plate joints did not exhibit significant differences in mean resistance between tension and compression loading for particleboard except for the largest #S-6 plates. The lodgepole pine group also exhibited larger variation in bending-moment resistance than the particleboard group. In all the wood-plate joints, the substrate was the point of failure. This study provides a preliminary database of strength values for the engineering wood-plate joint constructed of both lodgepole pine and particleboard.
