 note = {application/pdf, ln order to clarify the vibration characteristics of the traditional wooden pagoda with three-storied of Shinraku-ji temple, the microtremors and the vibration tests by man-powered excitations were carried out before and after repairs of this pagoda. From microtremors, three predominant frequencies and modes were obtained, as 1.5Hz, 2.3Hz and 3.7Hz, respectively. From vibration tests, the damping coefficient of 1st mode frequency of the Pagoda was obtained as about 0.03. Comparing the vibration characteristics of the pagoda before and after repairs, the natural period was slightly increased (7%). Furthermore, the aseismic isolation effect of the center pillar of the pagoda was examined by the method of Tuned Mass Damper (TMD).},
