Abstract

The development of cable-stayed bridge as a structural choice for medium to long span bridges has been remarkable through the closing decades of the last century. As an essential component of the bridge structure, stay cables play an important role in the dynamic behaviour of cable-stayed bridges. Cables are extremely vulnerable to wind excitation mainly due to its low mechanical damping. Many efforts have been made during the past years to clarify the mechanisms of, and find solutions to, various types of wind-induced cable vibrations to alleviate engineering problems. Furthermore, with a rapid development of span length in cable-stayed bridges, even new types of instability particularly of the inclined cables have been identified, such as the rain–wind vibration, high-speed vortex excitation, and the dry inclined cable galloping, which have been all new challenges to bridge engineers. The purpose of this chapter is to attempt a comprehensive state-of-the-art review of various types of wind-induced cable vibrations.
