| Research Abstract |
A new design strategy is required to achieve a higher performance seismic isolation system, which satisfies multiple design criteria for multiple earthquake input levels; a moderate input level as frequently experienced one, a severe input level as the design input level, and an extreme input level. This research work developed new energy dissipating devices that changes their control properties in direct response to isolator displacements, and proposed the "displacement design" strategies for seismic isolated buildings, which enabled more efficient displacement control of isolator displacement without increasing floor response accelerations in the superstructure.
