To realize this system, there were two challenges to be overcome. One was how to support a huge mass that has to move in any direction, and the second was how to control mass displacement that reaches about 2 meters. A simple pendulum mechanism with strong wires was adopted to solve the former problem. As a solution to the important latter problem, we developed a high function oil damper with a unique hydraulic circuit. When the mass velocity reaches a certain value, which was predetermined by considering the permissible displacement, the damper automatically and drastically increases its damping coefficient and limits the mass velocity. This velocity limit function can effectively and stably control the mass displacement without external power. This paper first examines the requirements of the TMD using a simple model and clarifies the constitution of the actual TMD system. Then the seismic upgrading project of an existing high-rise building is outlined, and the developed TMD system and the results of performance tests are described. Finally, control effects for design earthquakes are demonstrated through response analyses and construction progress is introduced.
