Abstract
The assessment of the structural performances of existing timber structures and eventually the design of any strengthening intervention require the diagnosis and a reliable mechanical identification of timber members, possibly through on-site inspections. Nowadays visual strength-grading is the only method regulated by the Code through which professionals can address this issue. However, being a superficial analysis, it has some limitations. Thus, non-destructive techniques (NDT) result to be advantageous supporting tools. Specifically the paper focuses on the application of the drilling resistance technique. Based on a statistical regression law matching the experimental data acquired from literature, a method for the determination of the mechanical properties of timber is proposed, providing a satisfactory approximation on the safe side.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
