Abstract

The dynamic performance of base-isolated buildings can be improved by introducing a tuned mass damper (TMD) at basement, below the isolation floor where most of the earthquake-induced displacement demand is concentrated. In order to enhance the effectiveness of the TMD without simultaneously amplifying the relevant mass ratio, the use of supplemental inertial mass dampers has been envisaged by the authors and other authors in earlier studies. These schemes exploit the mass-amplification effect of the inerter, a two-terminal device whose generated force is ideally proportional to the relative acceleration between its terminals. In this paper, we present a review along with a systematic comparative study of six different strategies proposed in the literature, each one featuring a specific combination of mass-spring-dashpot elements arranged in series or in parallel with an inerter for the displacement mitigation of base-isolated structures. Frequency-response functions of each model are derived in closed form. Optimal design is based on a common strategy, considering a white-noise random process as seismic input, by minimization of the displacement variance but with an eye also for the superstructure acceleration (associated with forces arising in the superstructure) and for the TMD stroke. Then, the seismic performance of the six systems is assessed considering an ensemble of 52 natural earthquake ground motions, by comparing several response indicators including TMD stroke, deformation of the base-isolation floor, superstructure acceleration, interstory drifts, base shear, and reactions associated with spring, oil damper, and inertial damper supporting the TMD, which are significant for outlining preliminary economic assessments.

  • An inerter-based damper with a smaller mass ratio can lead to higher vibration control than a TMD with a higher mass ratio, provided a reasonable choice of the inertance ratio is made and the inerter is grounded.

    “It has been demonstrated that an inerter-based damper with smaller mass ratio can lead to higher vibration control than a TMD with higher mass ratio, provided a reasonable choice of the inertance ratio is made and the inerter is grounded [16,17].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
