Abstract: Current methods for deriving Young's modulus (E) from flexural resonant column tests do not account for the Timoshenko beam effect. Hence, the extent of the Timoshenko beam effect is investigated in this study using a series of numerical experiments performed by finite element program LS-DYNA. Prior to conducting the numerical experiments, LS-DYNA is verified for a cantilever beam to ensure that it is capable of accounting for the Timoshenko beam effect. The Young's modulus determined with the existing interpretation method for flexural resonant column tests, which does not consider the Timoshenko beam effect, is underestimated on average by about 11% for a typical resonant column specimen. A correction factor is proposed here to account for the Timoshenko beam effect using the existing interpretation method for flexural resonant column tests.
