Abstract
This study was to examine the effect of end pressure on the mechanical properties and delamination resistance of structural black spruce (Picea mariana) finger-joined lumber made of a short (12.7-mm-long) finger profile. End pressures used were 2.00, 3.43, 6.00 and 8.00 MPa. 8.00 MPa yielded the greatest 5th percentile ultimate tensile strength, but caused cracks at tips of a joint. It was recommended that 2.00 MPa be used as the optimized end pressure from the viewpoint of energy saving.
