Abstract
Withdrawal testing is being used for various reasons such as testing hypotheses on durability or developing new connectors using various screw-types or nails. New research questions extend these testing methods to other topics such as rammed-in electrodes for moisture content determination by the electrical resistance method. Three Australian wood species, Corymbia maculata, Eucalyptus nitens, and Pinus radiata D. Don., are therefore investigated using a fixed load rate. This paper outlines the methodologies employed in withdrawal testing and highlights key findings. Preliminary results indicate that moisture variations affect the fit of any pin-shaped object in wood, impacting their withdrawal load peak values. These findings contribute to understanding the impact of moisture on contact pressure and withdrawal capacity, crucial not only for designing reliable timber connections in construction, but also other applications such as wood moisture determination.
