WOOD SCREW WITHDRAWAL RESISTANCE OF SOME IMPORTANT TREE SPECIES GROWING IN EASTERN BLACKSEA REGION

Öz

This study was carried on the screw withdrawal resistance of stem wood material of Fagus orientalis Lipsky., Alnus glitunosa subsp. barbata (C.A.Mey) Yalt., Castenea sativa Mill., Picea orientalis (L.) Link., and Pinus sylvestris L. The wood samples of these tree species were collected from forest districts in Gümüshane, Trabzon and Artvin. Tests were carried out according to the TS 6094 and ASTM-D 143 and ASTM-D 1761 on 60 samples of each one of the tree species. Half of the samples were 12 % and the other half were 30 % moisture contents. The dimensions of wood materials on which the tests carried out are 50 x 50 x 150 mm. Screws used for withdrawal tests were 4.5 mm in diameter and 40 mm in length. Two screws were inserted into lead holes at right angles on the tangential surface, 26 mm penetration. The results showed that the highest screw withdrawal resistance was found for oriental beech among the five tree species. The order of screw withdrawal resistance from the higher to the lower was found as fallows; alder, chesnut, pine, spruce. In regards to moisture effects, the screw withdrawal resistance were found higher at 12 % moisture content.
