“…However, in [10], the bending stiffness of the cable has been omitted. In [11][12][13] the damping of a cable with bending stiffness and a viscous damper attached at an intermediate point has been studied.…”

“…A maximal damping rate for the second mode can be achieved when the damper is located at the 1/4th point of the cable. In [10] the effect of the spring stiffness, the damping parameter, and the mass of the attached TMD on the damping properties of the first oscillation modes of the cable have also been studied.…”

“…Recently, in [10], the damping properties of a cable with an attached TMD have been examined. Here it has been found that the damper reaches a maximal damping rate for this first mode of the cable with attached damper, when the damper is tuned to the first natural frequency of the cable and installed at the midspan of the cable.…”

Cables are widely used structural elements capable of bearing tensile forces and experience vibration problems due to their slenderness and low mass. In the field of civil engineering, they are mostly used in bridges where the vibrations are mainly induced by wind, rain, traffic and earthquakes. This paper proposes the use of a tuned-inerter-damper (TID) system, mounted on cables to suppress unwanted vibrations. These are to be attached transversally to the cable, in the vicinity of the support, connected between the deck and the cable. The potential advantage of using a TID system consists in the high apparent mass that can be produced by the inerter. Our analysis showed that the modal damping ratio obtained is much higher than in the case of traditional dampers or tuned mass dampers, leading to an improved overall response. An optimal tuning methodology is also discussed. Numerical results are shown with a cable subjected to both free and forced vibrations and the TID performance is improved when compared with equivalent dampers.

This paper presents a prestressed sliding wedge damper as an effective alternative for the reduction of vibration amplitudes. Due to the system's non-smooth and non-linear characteristics, it offers advantages over conventional linear dampers, e.g an amplitude adaptive behavior. First, the equations of motion which describe the system's characteristics are derived. Second, an analytical model based on a modal coordinate transformation and averaging methods is proposed. A numerical model, which uses an elasto-plastic contact model is set up, in order to fully model the systems behavior. An analysis of the dampers characteristics shows that it is a pseudo-viscous damper realized via dry friction. The analytical and numerical results are compared and show a reasonable agreement, as within asymptotic methods. This work presents the first investigations into prestress influence on such a damper and offers insight into future theoretical, numerical, and experimental analysis.
