Stable economic growth and the social development of most countries are intimately dependent upon the reliable and durable performance of their structures and infrastructures. Natural hazards, ageing and functionality fluctuations can inflict detrimental effects on the performance of structural systems during their lifetime. Even the inherently conservative initial design of structural systems may not protect them from such threats.
In order to improve the lifecycle performance of engineering structures subjected to dynamic hazards (earthquakes, wind, traffic, machinery, sea waves etc.), considerable research attention has been devoted to developing and optimising a variety of vibration control strategies, successfully applied to both new and existing structures in the different fields of civil, marine, mechanical, transportation, nuclear and aerospace engineering. These strategies, encompassing passive/active/hybrid/semi-active systems and include, among others, base isolation, dissipation enhancement and resonant absorption, can efficiently contribute to an enhanced safety and serviceability of structures and infrastructure systems, reducing their operational costs and lifetime vulnerabilities.
Despite these efforts, further advancement is still needed, especially aimed at evaluating and comparing alternative vibration control paradigms in a lifecycle perspective, in order to ultimately show their cost-effectiveness in meeting long-term requirements of structural safety, robustness, serviceability, durability and sustainability.
This special issue is dedicated to the various aspects of the theory and application of dynamic vibration control as a means to improve the life-cycle performance of engineering structures. Both original research papers and state-of-the-art reviews are welcome; high-quality papers, balancing theory and practice and presenting experimental results, are particularly encouraged.
