We installed a tuned mass damper (TMD) on the top of a high rise building as a countermeasure against long-period earthquakes. When a TMD is applied to an existing high-rise building, the size of the TMD tends to be increased to synchronize with the frequency of the building. Therefore, we developed a compact TMD that can be installed in a penthouse. The weight of the iron mass was 1400 t, which was approximately 2.4% of the superstructure’s weight. Rubber bearings and bi-directional linear sliders were used to support the mass of the weight. Oil dampers were used to absorb the vibration energy of not only earthquakes but also strong wind. We adopted a larger value for the coefficient of damping than the theoretical value based on fixed-point theory so that we could fit the TMD within the building.
