Abstract

Liquid column dampers (LCDs) have long been used for the seismic vibration control of flexible structures.In contrast, tuning LCDs to short-period structures poses difficulty.Various modifications have been proposed on the original LCD configuration for improving its performance in relatively stiff structures.One such system, referred to as a compliant-LCD has been proposed recently by connecting the LCD to the structure with a spring.In this study, an improvement is attempted in compliant LCDs by replacing the linear spring with a spring made of shape memory alloy (SMA).Considering the dissipative, super-elastic, force-deformation hysteresis of SMA triggered by stress-induced micro-structural phase transition, the performance is expected to improve further.The optimum parameters for the SMA-compliant LCD are obtained through design optimization, which is based on a nonlinear random vibration response analysis via stochastic linearization of the force-deformation hysteresis of SMA and dissipation by liquid motion through an orifice.Substantially enhanced performance of the SMA-LCD over a conventional compliant LCD is demonstrated, the consistency of which is further verified under recorded ground motions.The robustness of the improved performance is also validated by parametric study concerning the anticipated variations in system parameters as well as variability in seismic loading.

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.
