In the tests, randomly selected logs taken from the trunk 2-4 m height were obtained from trees naturally growing in And›r›n (Northeastern Mediterranean region) and these logs were prepared and tested according to Turkish standards. The results showed that the mean compression strength was 606 kgcm-2, static bending strength 1204 kgcm-2, impact bending strength 0.85 kgmcm-2 and shear strength 99 kgcm-2. The relations of strengths with density were determined with regression analyses, and these were compared with other available values in the literature. As a result of this comparison, it was observed that Eastern beech trees growing in And›r›n and other beeches have similar mechanical properties and density.
