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...

The paper presents the semi-active vibration control based on the Skyhook algorithm which benefits from the adaptively tuned inverse magnetorheological (MR) damper model. The structure of the inverse model consists of the atan function and a linear viscous damping component. The proposed algorithm was tested by simulation of the quarter-car suspension model subjected to multiple bump road excit...

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...

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...

Steel-concrete composite girder bridges, in essence, are thin-walled structures, the dynamic responses of which will be greater than those a typical Euler–Bernoulli beam under train-bridge interaction because shear lag and interface slip. Thus, this study, analysis model train-composite box bridge-multiple tuned mass damper (MTMD) coupling system is proposed, with derived equations time-varying...
