The variable damper using Magneto-Rheological fluid (MR damper) changes its damping force by changing the magnetic field acting on the MR fluid according to an electric current. Semi-active control using such a variable damper stabilizes building responses in an earthquake better than the conventional passive control. Basic characteristics of the MR damper have been clarified. This time, authors proposed control algorithm of base-isolation structure, which applied the optimal regulator theory. This control algorithm reduces response displacement and response acceleration for the purpose of, and aims at enhancements, such as safety and amenity. This paper describes shaking table tests on a three-story large-scale test frame with base-isolation structure. The test results verify the controlling system and the control effect as a semi-active device of the MR damper.
