Details | In this paper, through the real-time-hybrid experiment with the use of “MR rotary inertia damper” the authors have been developed, the seismic response properties are discussed by changes in the parameters on building structure. The setup parameters in this paper are three of the followings; natural period of building structure, inertia mass ratio to building structure mass and variety of input earthquake motion. From the knowledge obtained by the experiment, the authors propose the semi-active control method focused on input velocity of earthquake. Then, in comparison between passive control and semi-active control, it have been confirmed the effects of the displacement reduction in the all case of experiments performed in this paper. Especially, in the case of JMAKobe earthquake, by the proposed semi-active control, it have been confirmed both floor response acceleration and displacement were reduced. |
