| Abstract: |
In this study specimens cut from intermediate timber floor beams that have been in service for more than 120 years were tested. The objective of this paper is to determine the strength characteristics and stiffness modulus of old wood and examine relationships between different properties. Experimental tests for determining the mechanical properties in bending have been carried out in short-term static loading. Also shear strength and compression strength perpendicular to the fiber direction was determined by tests. It is concluded that the modulus of elasticity of wood during long-term service under load decreases faster than the strength properties. When evaluating the relationship between wood strength and stiffness properties, a weak correlation was found between bending strength and modulus of elasticity. As well as other properties (density, moisture content etc.) didn’t show any remarkable correlation significance. |
