Abstract
The bending moment resistance under diagonal tensile load of doweled joint in plywood members was investigated. Joint members were cut from 11-ply hardwood plywood (Beech, Hornbeam and Alder) at the nominal thickness of19 mm. Dowels were made of Beech and Hornbeam woods. Dowel diameters (6, 8 and10 mm) and depths of penetration (9, 13 and17 mm) in the joint members were selected as variables. The effect of dowel variables on the bending moment of the corner joints was evaluated. Results showed that the dowel diameter, penetration depth and species exerted a significant effect on the bending moment resistance under diagonal tensile load. Bending moment resistance under diagonal tensile load was increased as the diameter of the dowel increased from 6 to8 mmand as the penetration depth of dowel increase from 9 to13 mm. However, increasing the diameter from 8 to10 mmor the penetration depth from 13 to17 mmhad no significant effect on bending moment resistance under diagonal tensile load. Results also indicated that bending moment resistance of joints made with beech wood dowels provided higher resistance than hornbeam dowels.
