Wood Moisture and Compressive Strength

Red Spruce, Longleaf Pine and Douglas Fir - moisture content and compressive strength

Moisture content versus compressive (parallel to grain) strength for Red Spruce, Longleaf Pine and Douglas Fir are indicated in the graphs below:

wood moisture content versur compressive strength

Indicated strengths are relative to wood containing 2% moisture. 

  • Red Spruce - air dried : 14% moisture content, kiln dried : 6% moisture content
  • Longleaf Pine - green wood : 20 % moisture content
  • Douglas Fir - green wood : 24 % moisture content
