This paper investigates the use of inerters for vibration suppression of a multistorey building structure. The inerter was proposed as a two-terminal replacement for the mass element, with the property that the applied force is proportional to the relative acceleration across its terminals. It completes the force-current mechanical-electrical network analogy, providing the mechanical equivalent...

This paper considers the use of a tuned inerter damper (TID) system for suppressing unwanted cable vibrations. The TID consists of an inerter, a device that exerts a force proportional to relative acceleration, coupled with a parallel spring and damper. It may be thought of as similar to a tuned-mass-damper, but requiring two terminals. As a two terminal device, the performance of the TID is co...

Control of high-rise structures under seismic excitations was investigated using a passive hybrid control system consisting base-isolation (BI) subsystem and tuned liquid column damper (TLCD) system. Both the systems were optimized considering other in same structure. An optimization method developed, computer code written based on dynamic analysis structure metaheuristic methods. Within scope ...

this study is investigated the optimum parameters for a tuned mass damper (tmd) under the seismic excitation. shuffled complex evolution (sce) is a meta-heuristic optimization method which is used to find the optimum damping and tuning frequency ratio for a tmd. the efficiency of the tmd is evaluated by decreasing the structural displacement dynamic magnification factor (ddmf) and acceleration ...

Early telemetry from the spin-stabilized IMAGE spacecraft indicated that the vehicle’s initial nutation was not decaying. This behavior was especially puzzling because the spacecraft’s passive nutation damper behaved as expected while IMAGE was attached to the spinning upper stage. The lack of damping was also puzzling because the damper was a tubular ring partially filled with liquid mercury; ...

Abstract This paper explores the use of a novel tuned-inerto-viscous-hysteretic-damper (TIVhD) for reducing seismic response multi-storey building structures. The TIVhD is an inerter-based damper device consisting linear hysteretic connected in series with inerto-viscous damper. layout similar to that tuned-inerter-hysteretic-damper (TIhD) additional viscous damping element parallel inerter. de...

In this paper, the two-dimensional vibration controls of a power transmission tower with a pounding tuned mass damper (PTMD) under multi-component seismic excitations are analyzed. A three-dimensional finite element model of a practical power transmission tower is established in ABAQUS (Dassasult Simulia Company, Providence, RI, USA). The TMD (tuned mass damper) and PTMD are simulated by the fi...
