Abstract
In this study, evaluation for seismic behaviors of inter-story isolated building structures and proposition of effective synthesis for inter-story isolating systems are focused. Emphases are put on following items: 1) To make assure fundamental characteristics of seismic responses of inter-story isolated buildings, 2) To estimate influences of aseismic behaviors of inter-story isolated buildings under considering soil-structure interactions. Through parametrically numerical simulations, those items are investigated in detail. As more advantageous idea to improve efficiency of inter-story isolating systems, additional installations of hysteretic damping devices are pointed out and estimated. As a result, it is assured that more effective response reductions can be gained by introducing the additional hysteretic devices on the lower stories below isolating floor.
