摘要：
It is recognized that a base-isolated building exhibits a large response to a long-duration, long-period ground motion and an interconnected building system is not necessarily effective for a pulse-type ground motion. To compensate for each deficiency, a new hybrid passive control system is investigated in which a base-isolated building is connected to another building (free wall) with oil dampers. It is shown that the mechanism of response reduction in the proposed hybrid passive control system is closely related to the property of natural frequency and damping ratio with respect to increased capacity of connected dampers in a translation mode and a meeting-parting mode. © 2017 Architectural Institute of Japan.
