There are many factors that affect the mechanical properties of laminated veneer lumber (LVL), such as the thickness of veneer, the compression ratio, the wood species and the density of LVL. In this paper, two different nondestructive testing (NDT) methods and the static shearing test were conducted on the birch (Betula platyphylla Suk.) LVL. The NDT methods included the flexural vibration method and surface wave propagation method. The effects of the compression ratio of LVL on the dynamic shear modulus and shear strength of LVL were investigated. The results showed that the dynamic shear modulus and shear strength of LVL were increased with the compression ratio of LVL increased, the increase tendency of NDT results and static shearing test results were consistent.
