| Details | This paper shows fundamental properties of the damper authors have been developed with the aim of vibration control of building structures. The damper developed by authors uses both the mass effect by rotary inertia and the variable damping effect by magnetorheological fluid. In this paper, authors make a 100kN type test model of the damper developed, and experiment to bring out its performances with vibration tests by sine wave input, etc. In sine wave tests, the negative spring property by inertia mass and significant energy absorption by MR fluid are confirmed. Authors also confirm the validity of theories and analytical method on knowledge from performance test. And authors intend to carry out practical realization of rotary inertia mass damper using MR fluid. |
