- Abstract
- The use of logs for construction dates back millennia but has been largely supplanted by materials such as concrete, steel, and squared timber that allow for much more cexible and ebcient industrial processes. Recently, robotics and digital tools have reopened the possibility of using raw logs in modern building without relying on skilled craftsmen. However, the state of the art is still insubcient in several fields such as the mechanical characterisation and classification of tree trunks, the development of ebcient and reliable log-to-log connections, the integration of finishing touches, the transmission of data between digital design tools and robots, and the design of ebcient log coors. This study focused on the development of a non-destructive industrial protocol for the mechanical characterisation and classification of logs subjected to bending. The originality of the proposed methodology lies in its ability to guarantee the Ultimate Limit State (ULS), short-term Serviceability Limit State (SLS), long- term SLS and fire resistance of logs simultaneously. Developed through tests on green and dried large-scale logs, the protocol is easily transferable to industrial contexts. It also provides practical guidelines for integrating logs as load-bearing elements in construction.
