Abstract
<p>In this preliminary report, we report the results of comparing the stiffness and strength of timber for cultural property buildings by destructive and non-destructive tests. In the destructive test, full-scale specimens and defect-free small</p><p>specimens were tested by the three-point bending test method, and the defect-free small specimens showed higher strength. In the non-destructive test, the stress wave propagation method and the impact method were used for measurement, and the Young's modulus measured by the impact method tended to be partially low. There is a tendency for the stiffness to be relatively close to the correlation between the destructive test of the full-scale specimen and the non-destructive test by the stress wave propagation method, this result showed the same trend as the result that the dynamic test value is generally said to be higher in stiffness than the static test value.</p>
