3. Introduction
Major issues related to strength prediction of bonded joints involving timber adherends

  • Timber has to be considered as a brittle material

4. Timber mech props have a rel. high variability 5. Stresses in the bonded splice are characterized by high peaks, especially both y and xyAs a result

  • Any stress based prediction method is deemed to fail
