In many cases, conventional mass dampers with additional weight on the building tops have been installed for the purpose of improving the habitability against strong wind. However, it has been rare for mass dampers to be used as countermeasures against earthquakes. We have developed a large-scale vibration control system utilizing the whole weight of building top floors to serve as mass dampers. The building used for our study on mass dampers is a high-rise R.C. structure, about 162 meters high at the highest point, with forty-three stories above the ground. Based on the seismic response analysis using the artificial earthquake waves, the natural vibration period of the mass damper was tuned so as to decrease the story drift of the whole building remarkably. If the building is assumed to be elastic, the optimum frequency of the mass damper is 3.8 sec., equivalent to the theoretically estimated from the primary natural frequency of the building. On the other hand, if the building is assumed to be elasto-plastic, the damper becomes the most effective when the frequency is tuned to about 8.0 sec. With the mass damper, the maximum story drift of the building is reduced by about 20%.
