Abstract Inerter-based vibration absorbers (IVAs), such as the tuned-mass-damper-inerter (TMDI), have become popular in recent years for earthquake protection of building structures. Previous studies using linear structural models shown that IVAs can achieve enhanced suppression, but at expense increased control forces exerted from IVA to host structure. The authors recently developed a bi-obje...

Abstract In recent years, the tuned mass damper inerter (TMDI) has been demonstrated in several theoretical studies to be an effective vibration absorber for seismic protection of non-isolated buildings. Its effectiveness relies on careful tuning TMDI stiffness and damping properties, while its performance improves with increase inertance property which is readily scalable. Nevertheless, all pr...

We present a probabilistic methodology for designing tuned mass dampers for flutter suppression in long-span bridges. The procedure is computationally efficient and computes the probability of flutter occurrence based on a modified first-order method of reliability analysis, a reduced-order representation of the structure and a time domain formulation of aeroelastic loads. Results of a parametr...

A series of wind tunnel model tests and theoretical analyses were conducted to investigate torsion excitation, response and vibration suppression of wind-excited buildings. An aeroelastic model for pure torsion vibration was developed and the aeroelastic test results were compared with those obtained by other Wind tunnel test techniques. The comparison and practice indicated that this type of m...
