Analysis of the TMD Enhanced Base Isolation System (BIS) Using Clutching Inerter Damper
Publication: Earth and Space 2021
ABSTRACT
This paper presents an enhanced base isolation system (BIS) by involving the tuned mass damper (TMD) in series with clutching inerter damper (CID), mounting in the isolation layer, which is similar to the conjunction use of the BIS and the tuned-mass-damper-inerter (TMDI); the difference is that the inerter in the TMDI is replaced by the CID. Compared with the TMD enhanced BIS, the proposed control strategy has better control for the displacement of the isolation layer and the superstructure. Comparing with the TMDI enhanced BIS, the proposed control strategy has better control for the TMD stroke because of the superiority of the CID over the inerter.
