When we evaluate the structural characteristic of traditional wooden structures, it is useful way to estimate vibration characteristics from micro-tremor measured data. In this study, we conducted micro-tremor measurements and excitation tests on Chofuku-ji Hondo in Ikoma City, Nara pref. and estimated the natural frequency, the damping ratio, and so on.Moreover, we made the analysis model of the building, and made sure of the differences between analytic and measured values by eigenvalue analysis.
