This study investigates use of bamboo as a small diameter fastener within timber connections. A comparison of strength, stiffness, ductility and failure mode was made between hot-pressed bamboo, normal bamboo and metal nails. The application of bamboo nails within multiple fastened timber connections has been assessed through testing two different joint layouts in single shear. The results show that hot-pressed bamboo nail connections could achieve about 65% of ultimate strength of metal nail connections in both layouts. It was also observed that the layouts of the nails have an effect on the mechanical properties of dowel type connections. The results from these tests were applied in the theoretical calculations for the nailed connections. It has shown that the beam on an elastic foundation theory provide acceptable predictions for stiffness and deflection.
