A new intelligent isolation system combining a piezoelectric damper with laminated rubber bearing is proposed. and used in a practical example in this paper, LQR and GPC chose as the control algorithm according to the damper. The characteristic of these two kinds of algorithm is analyzed and is used in the civil engineering vibration controlling. The results of the analysis show the performance...

This article presents the development of a novel magnetorheological damper which has a self-sensing ability. In this study, a linear variable differential sensor, which was based on the electromagnetic induction mechanism, was integrated with a conventional magnetorheological damper. The working principle, configuration, and prototype of the displacement differential self-induced magnetorheolog...

Friction-based dampers are a valid solution for non-invasive seismic retrofitting interventions of existing structures, particularly reinforced-concrete (RC) structures. The design friction-based is challenging: underestimating the slip force prevents full use potential device, which attains maximum admissible displacement earlier than expected. By contrast, overestimating may cause delayed tri...

This study aims at assessing the use of a novel damper, which is called Prestressed LEad Damper with Straight Shaft (or PS-LED), for seismic rehabilitation RC framed buildings. device provides high energy dissipation by friction activated between lead core and shaft achieves specific output force preloading during assembly. In order to show effectiveness PS-LED retrofit existing buildings, stru...

This paper presents the effect of friction-induced vibration between two beams in relative motion according to Timoshenko’s beam theory. system is composed cantilever screwed together, allowing friction force occur contact interface. The nonlinear behavior can be divided into phases: stick and slip. differential equations phases are developed, with precision transition condition each phase. A n...
