Strength grading of structural timber
Considering the spontaneous growth of trees in forests and genetic variability due to environmental factors, wood is characterised by a wide variability of mechanical properties. Modern structural timber design systems, which lead to the CE marking of structural products, are established to work with characteristic strength values whose variability is under strict statistical control. This check is based on a selection of the properties of wood that influence its strength and can be assessed by visual or machine grading.
The webinar is organised into the following thematic sections:
- Evolution of structural timber in Europe
- Characteristic values of wood
- Visual grading
- Machine grading
- Standards for the CE marking of structural timber

An associate professor at the University of Florence since 2001, he holds a degree in Forest Sciences from the University of Florence and a PhD in Wood Science from the same university in 1995. His main fields of research concern timber for structural use: evaluation of the mechanical properties of ancient timber structural elements and structural systems, in situ inspection and diagnosis, characterisation of timber for structural use. He is involved in regional and national research on timber quality, uses and characterisation.
