Cable vibration damper

To eliminate uncomfortable swaying caused by pedestrians deliberately shaking its slender stay cables, a cable-stayed footbridge in Felcsút, Hungary, was retrofitted in 2023 using specialized rotational friction dampers. Each cable was fitted with an orthogonal pair utilizing a rhombus damper mechanism tucked discreetly below the handrails. This compact setup successfully dissipated hand-forced vibrations, drastically reducing cable sway and stabilizing the bridge deck while preserving its distinctive swan-inspired aesthetic.
