Vibration control of multi-degree-of-freedom structures using multiple tuned mass dampers and higher-order exceptional points

Tuned mass dampers are among the most widely used devices for suppressing resonant vibration in buildings and other flexible structures, yet their behaviour on a multi-degree-of-freedom host with non-proportional damping is still only partly understood. This paper analyses a structure controlled by several tuned mass d...

Asymptotic- and bifurcation-aware scientific machine learning for nonlinear vibration prediction of submerged floating tunnel tethers under hydrodynamic excitation

Seabed-anchored submerged floating tunnels transmit most of their transverse stiffness to slender pre-tensioned tethers whose vibration governs the fatigue design of the crossing. A reduced-order model represents the tunnel cross-section as a two-degree-of-freedom rigid tube coupled to small-sag tethers, linearizes the...
