Abstract :Traditional destructive testing is used to determine the mechanical properties of construction timber. Although accurate results are obtained from these tests, they damage the material and render it unusable. As a result, the tested material cannot be reused, resulting in economic losses. In addition, destructive methods require a laboratory infrastructure to perform the tests and do not provide on-site evaluation. Due to these disadvantages of destructive testing, non-destructive testing methods have emerged. Non-destructive testing prevents cost loss by causing no or very little damage to the material, providing on-site testing and enabling the material to be reused. Based on this, this study aims to determine the technological properties of timbers of different resistance classes by non-destructive and destructive tests. For this purpose, non-destructive screw withdrawal force, shear modulus, density, bending strength and modulus of elasticity tests were performed on the timbers. In order to create a regression curve with these destructive tests, density, bending strength and modulus of elasticity tests were also performed destructively. A highly accurate regression curve was found using the data obtained as a result of the tests.
