Summary
Many long span bridges are built all over the world in order to meet the needs of transportation development. The increase in span makes the bridge more flexible and more sensitive to wind. Although the divergence flutter has been avoided by raising the critical wind speed of the flutter at design stage, it is difficult to avoid the occurrence of self-excited vortex-induced vibration. In addition, the increase of span reduces the natural frequency of the bridge structure, thus increasing the occurrence frequency of vortex-induced vibration at low wind speed. In recent years, vortex-induced vibrations have been observed many times on many long-span bridges. Vortex induced vibration is a large amplitude vibration phenomenon caused by the vortexes periodically shedding from the structure surface. Although the self-limited characteristics of vortex induced vibration do not directly lead to the structural dynamic instability, large-amplitude vortex-induced vibrations threaten driving safety and cause fatigue damage to bridge structures, which has an impact on the applicability and durability of the structure ( In extreme cases, it may result in damage or fracture of the main members of the structure, and even induce local or overall collapse of the structure). Therefore, it is of great significance to study the vortex-induced vibration of long-span bridges.
The proposed aim of this Special Issue is to present current state-of-the-art research in the field of vortex induced vibration of the long-span bridge including the field measurement, wind tunnel experiment and numerical simulation. We welcome original research articles that focus on the numerical simulation of fluid and structure interaction, the prediction and control of VIV of the prototype bridge, the structural health monitoring and damage identification and analysis of the long-span bridge. The studies of innovative equipment and techniques, high-precision reduced-order modeling and artificial intelligence methods as well as novel active and passive-control devices are encouraged. Note that review articles which describe the current state of the art are also welcome.
Potential topics include but are not limited to the following:
• Modelling of fluid and structure interaction of VIV
• Prediction of vortex-induced vibration of the prototype bridge
• Passive and active controls of vortex induced vibration
• Structural health monitoring, damage identification and analysis of the long-span bridge (big data and artificial intelligence methods)
• New observation equipment and experiment technology
