Abstract

The purpose of this paper is to verify the accuracy of a density estimation method for columns of traditional timber buildings and to improve applicability of the method to actual buildings in repair site. In this paper, a specimen with hanging walls is used and the density of column is estimated from the changes of its fundamental frequency before and after adding weight. In the proposed method, the accuracy of density estimation increases as added weight gets heavier. Microphone measurement can estimate the density as well as accelerometer measurement although the accuracy is slightly lower.
