Accuracy in Estimating the Elastic Modulus of Timbers for Individual Part Using the Nondestructive Tapping-Tone Technique
The purpose of this paper is to investigate the measuring precision of the elastic modulus of structural timber members. The elastic modulus by a rupture test is compared with the elastic modulus obtained by the tapping-tone technique used for each part of the test specimens. 1. As a result of comparison of the elastic modulus between the destructive test and the nondestructive test, precise measurement is obtained, and their correlation coincides very well. 2. The elastic modulus tends to be lower at the part near the pith of member. This result is supported by a destructive test and nondestructive test.
