This approach is part of an experimental deconstruction/reconstruction project located in the Vosges “département” of France and led by the social housing landlord, VOSGELIS. The main constraint related to this intention of re-use is the obtention of the strength class of the elements, which is not recorded in the standards. The comparative study of different non-destructive technologies has shown that the values of the dynamic modulus of elasticity obtained by the vibrational method are closer on average (15%) to the actual value obtained by the bending tests than those obtained by the ultrasonic method (35%). A portable measuring bench suitable for deconstruction site was also developed during the study for an utilisation of vibrational method. The values of the dynamic modulus of elasticity obtained on this bench are close on average to the values of the modulus of elasticity obtained by bending tests executed on a test slab (13%). This study made it possible to extend the use of the NF EN 14082-2 + A1 standard to woods from building demolitions. However, these standard need to being adapt it to for the classification of that typology of wood, with a reference batch constituted of 15 to 20 samples. reuse mechanical characterisation non-destructive characterisation wood deconstruction Full Text Additional Declarations No competing interests reported.
