The vibration control effect in an actual structure of a vibration control damper using the fluid force of water is discussed in this study. The building where the damper was applied is a tall panoramic tower 158 m in height. The damper was installed to reduce vibration of the building in the transverse direction due to wind. Forced vibration experiments, free vibration tests, microtremor measurements, and wind vibration observations were carried out for cases with and without the damper in order to verify the vibration damping effect of the damper. The following conclusions were drawn as a result of these tests and observations: (i) It was ascertained that this vibration control damper was effective against steady-state and random forces. (ii) The calculated value according to the analysis technique proposed corresponded well with experimental values.
