Abstract
AbstractAmid increasing concerns about the occurrence of mega earthquakes, recent studies have shown that the deformation of conventional seismic isolators may exceed their expected design range. To address this issue, we have been developing a displacement-control system for seismic isolation equipped with high-static-low-dynamic stiffness and rotational inertia. In this paper, we report the results of large shaking-table experiments involving a comparison of the response of a seismic-isolation model of our displacement control system we developed to that of a time-response analysis model we constructed on the basis of our model.KeywordsSeismic isolationDisplacement control systemHSLDSRotational inertiaShaking table test
