Structures with a high slenderness ratio and flexible forms, such as chimneys and steel towers, or those supported by cables like cable cars, respond sensitively to wind loads. When excessive vibration occurs, it can lead to fatigue in structural members or increase anxiety among passengers, making vibration control measures essential.
Vibration control devices are typically applied to structures vulnerable to wind loads and are also installed to reduce harmful vibrations affecting transportation systems, thereby improving passenger ride comfort.​
