ABSTRACT = {The bamboo scrimber is an anisotropic material. The elastic constant values of the bamboo scrimber specimens
measured by the dynamic and static methods are consistent, and the dynamic test method has the advantages of
rapidity, simplicity, good repeatability, and high precision. Bamboo scrimber has strong potential as a building
material, and its elastic constant is an important index to measure its mechanical properties. To quickly, simply,
non-destructively, and accurately detect the elastic constant of the bamboo scrimber, they were dynamically tested
by the free plate transient excitation method and cantilever plate torsional vibration method. The static four-point
bending method was used to verify the accuracy and reliability of the dynamic elastic modulus, shear modulus,
and Poisson’s ratio of the bamboo scrimber. The mechanism analysis and evaluation of the quality grade, homogeneity, and size effect of the bamboo scrimber whole board were carried out. The main results show that the
dynamic elastic modulus, shear modulus, and Poisson’s ratio of the bamboo scrimber are 12 GPa, 1500 MPa,
and 0.31, respectively, which meet the requirements of GB/T 40247-2021 for structural bamboo scrimber.},
