In this paper, the development of non-linear building isolation systems is overviewed. The study summarizes commonly used linear in two categories, which are base and inter-storey systems. Typical isolators including Lead-Rubber Bearings Friction Pendulum viscous damper Tuned Mass Damper reviewed. analysis design also reported. After that, introduced from aspects based on their dynamic characte...

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...

The study deals with the damage control system of wooden houses using wood friction-based dampers subjected to earthquake motion. In this study, friction joints were developed introduce damping into shear walls. Shaking table tests also conducted investigate seismic performance two-story timber structures composed plywood walls, plasterboards and walls high devices. purpose is propose an estima...

A damping strategy using a friction ring damper for an industrial flywheel was numerically and experimentally investigated. The damper, located on the arms of flywheel, found to effectively reduce vibration amplitude flywheel. energy dissipated when relative motions occur at contact interfaces. Nonlinear dynamic analysis based lumped-parameter model equipped with conducted. normal load, N, used...

Mathematical modeling and experimental research represented in this paper is aimed at dynamic force analysis of circuit cards order to eliminate or reduce stress deflection an acceptable level provide strength reliability design card assemblies subjected vibration. In conditions when viscous friction forces are negligible dampers, such as liquid cannot be used reduction oscillation amplitude cr...

The grand piano action has been developped empirically and provides a remarkably accurate control of the hammer velocity and the impact time [1]. The numerical simulation of the action is necessary to improve numerical keyboards and to better understand haptic controllability. Following previous efforts [2, 3], we propose a simulation based on an explicit model and a solver of non-smooth dynami...

This paper proposes a re-centering variable friction device (RVFD) for control of civil structures subjected to near-field earthquakes. The proposed hybrid device has two subcomponents. The first subcomponent of this hybrid device consists of shape memory alloy (SMA) wires that exhibit a unique hysteretic behavior and full recovery following post-transformation deformations. The second subcompo...
