Structural potential of reclaimed andlocal timber as new resources in the Netherlands

bookPart
The paper presents the results of a study aiming at an initial evaluation of the potential of two wood species grown within The Netherlands, as well as the potential of reclaimed material from Dutch deconstruction sites. A total of 28 pieces of Douglas-Fir, 49 pieces of Larch and 32 pieces of reclaimed spruce were first visually graded based on Dutch and German standards. Afterwards, the specimen were evaluated using stress wave and X-ray machine grading methods. Finally, the actual properties of the specimens were determined using four-point bending tests. The density, stiffness and strength results from bending test were directly compared to the mechanical properties assigned by visual grading to evaluate if appropriate grades were assigned. Furthermore, the bending test results were compared to the results from machine grading. The comparison showed good agreement with respect to stiffness and strength, while overestimations by the machine grading methods were noticeable.
