Farklı Direnç Sınıflarındaki Kerestelerin Bazı Mekanik Özelliklerinin Tahribatlı ve Tahribatsız Yöntemlerle Belirlenmesi

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.
