This paper presents the results of micro-tremor measurement of newly-built three-stories wooden pagoda. Five times measurements were conducted during construction and after completion. In each of the measuring result, it was able to confirm the first-order, second-order and third-order modes, respectively. At the last measurement, 1.6Hz of predominant frequency at the first-order mode was obtained. Also, the damping constants were measured by free vibration tests. Finally, the eigenvalue analysis was conducted by the lumped mass system. The ratios of second- and third-order natural frequencies to the first-order frequency obtained by measuring are the same as the analytical results.
