Abstract

This paper presents a new seismic response-control system which a new type of toggle mechanism is installed. The one of authors have indicated that the lever mechanism with auxiliary mass can reduce sufficiently the input effect such as earthquake ground motions under the severe condition that the stiffness of lever arm has very high keeping large arm ratios. This paper develops the toggle system in order to overcome this difficulties and derives theoretical formulas of this system. The theory and control effectiveness of the proposed system are confirmed through a series of shaking table test for the model structure with the toggle system.
