Vibration Suppression Using a Passive Reaction Mass Incorporating Inerters in a Multi-storey Building

Research output: Chapter in Book/Report/Conference proceedingConference Contribution (Conference Proceeding)


This paper investigates the use of a vibration suppression system consisting of a reaction mass connected to the structure at a single point via a combination of springs, dampers and inerters. The classical tuned mass damper (TMD) configuration is used as a benchmark. Specifically, a three-storey building model, with the device connected at the top floor, subjected to base excitation is analysed. In order to identify optimum absorber configurations, the structure-immittance approach is utilized, for minimising the maximum inter-storey drift. Using this approach, a full set of networks with pre-determined number of elements can be analysed systematically and the element parameters can be constrained or fixed at the same time. It is shown that with one damper, one inerter and no more than two springs, several absorber layouts can be identified with superior performance than a traditional TMD.
