标题：Real‐time hybrid simulation of semi‐active control using shaking table: Proposal and verification of a testing method for mid‐story isolated buildings
摘要：This study proposes a real‐time hybrid simulation method for semi‐active control using a shaking table. The method can be used for simulating a mid‐story isolated building. This simulation system uses a test specimen for the upper structure, a semi‐active damper that is installed in the base isolation layer on the shaking table, and a lumped mass system for a lower structure for the computer simulation. A rotary inertia mass damper that contains magnetorheological fluid is used in the semi‐active control. The semi‐active control cannot avoid a control time lag. This time lag is estimated by assuming a first‐order lag system. The experimental and analytical results considering a control time lag are compared in this study. The validity of the real‐time hybrid simulation is verified.
