Vibration Control in Structural Systems

Vibration control in structural systems encompasses a range of passive, semi-active and active techniques designed to mitigate unwanted oscillations induced by environmental loading, human activity or machinery. Lightly damped structures such as tall buildings, long-span bridges and offshore wind turbine towers are particularly vulnerable to dynamic excitation from wind, waves and seismic events. Uncontrolled vibration not only compromises comfort and functionality but also accelerates fatigue damage and reduces service life. Passive strategies rely on tuned mass dampers, inerter devices and specially configured isolators to absorb or redirect vibrational energy without external power. Semi-active approaches combine variable-property elements—such as magnetorheological dampers—with real-time feedback to optimise damping levels. Active control employs sensors, actuators and control algorithms to apply forces that counteract motion. Recent advances include mechanical metamaterials with programmable stiffness profiles, integ­rated inerter networks for broadband suppression and hybrid systems that harvest vibration energy while providing damping. By tailoring dynamic properties to specific modal characteristics, modern solutions can achieve substantial reductions in displacement, acceleration and stress across a wide frequency spectrum, thereby enhancing safety, resilience and longevity of infrastructure worldwide.

Recent investigations into vibration control have expanded beyond traditional tuned mass dampers to exploit inerter-based devices, metamaterials and hybrid reliability assessments. A study on floating offshore wind turbine towers demonstrated that equipping support structures with tuned mass damper inerters (TMDIs) significantly improves reliability under combined wind and wave loading. Multi-body dynamic models subject to stochastic excitation revealed that the inclusion of a TMDI reduces the vulnerability of side-to-side modes and lowers fragility across a range of misaligned loading scenarios. Another line of work introduced programmable quasi-zero-stiffness (QZS) mechanical metamaterials, in which curved beam geometries generate multiple low-stiffness regimes under compression. Experimental compression and vibration tests confirmed ultra-low-frequency isolation capabilities over adjustable working ranges, suggesting scalable solutions for compact isolation platforms. Foundational research on cable structures employed tuned inerter dampers (TIDs) comprising inerters coupled with springs and viscous elements to suppress conductor vibrations. Comparative analyses under support excitation showed that TIDs overcome inherent limits of conventional viscous dampers, offering elevated modal damping and reduced mid-span displacements. These diverse contributions illustrate a trend towards energy-efficient, frequency-tunable and multifunctional vibration control devices applicable to civil, offshore and mechanical systems.
