DescriptionThis research focused on evaluating the bending stiffness and strength of structural lumber with transverse vibration nondestructive testing techniques. A random sample of nominal 2-in.- (standard 38-mm-) thick Southern Pine dimension lumber was obtained from several mills in southeastern United States. After conditioning, the lumber specimens were nondestructively tested using transverse vibration techniques. Modulus of elasticity (MOE) was determined using the frequency of oscillation and density. Static bending MOE and strength were then determined for each specimen. Statistical analyses were then performed to examine the relationships between transverse vibration modulus values and bending MOE and strength. Excellent relationships were observed between transverse vibration and static bending MOE values. Strong relationships were found between transverse vibration MOE and bending strength.
