The effectiveness of Tuned Liquid Dampers (TLD) on a bridge deck in the lifting
phase against flutter instability is presented. The following study represents an
experimental investigation. A linear analytical approach was used for predimensioning
the TLD. Based on that, TLDs were built and tested on a shaking table. The
experimental results were not in good agreement with the analytical method therefore
new tanks were constructed in order to conduct the experiment in the wind tunnel. A
scaled model of the deck of Bosphorus Bridge is analyzed as an illustrative example.
The effectiveness of the TLD system in increasing the critical flutter speed of the deck
is investigated through a parametric study, which led to the optimization of
paramaters such as height of water or position of the water tanks which provide
maximum critical wind speed for the deck section. The result of the experiment shows
that the critical flutter velocity is increased compared to the deck alone, but the
tuning condition is not obtained since the tanks filled with water exhibit an in-phase
motion with the deck. This study may open a broad range of questions regarding the
utilisation of unconventional techniques for this particular problem and different
solutions may be tested and adopted given the variety of available techniques.

Passive vibration control plays a crucial role in structural engineering. Common solutions include seismic isolation and damping systems with various kinds of devices, such as viscous, viscoelastic, hysteretic, and friction dampers. These strategies have been widely utilized in engineering practice, and their efficacy has been demonstrated in mitigating damage and preventing the collapse of buildings, bridges, and industrial facilities. However, there is a need for more sophisticated analytical and numerical tools to design structures equipped with optimally configured devices. On the other hand, the family of devices and dissipative elements used for structural protection keeps evolving, because of growing performance demands and new progress achieved in materials science and mechanical engineering. This Special Issue collects 13 contributions related to the development and application of passive vibration control strategies for structures, covering both traditional and innovative devices. In particular, the contributions concern experimental and theoretical investigations of high-efficiency dampers and isolation bearings; optimization of conventional and innovative energy dissipation devices; performance-based and probability-based design of damped structures; application of nonlinear dynamics, random vibration theory, and modern control theory to the design of structures with passive energy dissipation systems; and critical discussion of implemented isolation/damping technologies in significant or emblematic engineering projects.
