Moisture content of structural finger-jointed southern pine following a durability cycle

Four batches of commercially manufactured structural finger-jointed southern pine were examined to determine wood moisture content (MC) following a durability cycle. The three batches that gained moisture during the durability cycle had larger differences in MC between the wood pieces within the finger-jointed specimens. One batch lost moisture during the durability cycle and had greater uniformity in MC between the wood pieces within the finger-jointed specimens. Methodology that accounts for variability in MC between the wood pieces within finger-jointed specimens may need to be considered in durability cycle requirements specified in existing standards. Additionally, because similar vacuum-pressure-soak cycles precede durability strength tests and glueline delamination measurements, further work that examines the effect of differences in MC between the wood pieces within finger-jointed specimens on these tests may be warranted.
