Abstract: The study summarized in this report was conducted to examine the relationships between nondestructive evaluation parameters and the modulus of elasticity (MOE) of spruce–pine–fir structural lumber. A random sample of lumber was obtained from a local lumber yard and conditioned to approximately 10% equilibrium moisture content in the laboratory. Static bending and vibration (transverse and longitudinal) nondestructive tests were conducted on each specimen, and MOE was calculated. The relationship between static and dynamic modulus values was examined, and empirical models were developed using statistical regression analysis techniques. Results revealed excellent correlative relationships between MOE values. Coefficients of determination obtained were 0.92, 0.96, and 0.93 for MOE of static– transverse vibration, MOE of static–longitudinal vibration, MOE of longitudinal–transverse vibration, respectively.
