A method for measuring the embedding characteristics of wood and wood-based materials

Embedment tests yield foundtion moduli and embedding strengths which can be input to beam-on-foundation models which predict the load-deformation behaviour of wooden joints with laterally loaded fasteners such as nails or bolts. Test procedures and apparatus suitable for standardized embedment tests on solid wood or wood-based sheet materials are described. The need for specimen fabrication techniques and specimen support arrangements which reflect the stress conditions for fasteners inserted into members of real joints is emphasized.
