Abstract
Rain - Wind Induced Vibrations of a cable is a concomitant issue in cable - stayed bridges which it will threats the durability and safety of the structures. A deep understanding the phenomenal of the Fundamental physics was important to understand for improving the effective remedies to resolve. This Concept was firstly observed several decades ago. It found the attention of investigators when Shiraishi and Hikami observed that, at the time of construction of the Meikonishi Bridge in Japan, under the excitation from the wind during rain, these stay cables often exhibited large-amplitude vibrations. Rain – Wind induced vibrations was identify by an oscillation frequency and also the large amplitude that is much lower than the comparable Strouhal frequency for a classical Karman – vortex induced vibrations, which it have been regularly observed on many cable - stayed bridges and stated as Rain – Wind - Induced vibrations. By the last three decades, Rain - Wind induced vibrations of Stay cable bridges have been subjected to extensive study for two reasons. Firstly this type of vibrations occurred at large amplitude and potentially threatens the serviceability and safety of cable-stayed bridges. There have been records in the literature of both cable failure and damage to the Cable Deck connection because of Rain – Wind induced vibrations. Also secondly, the mechanism of Rain – Wind induced vibrations, as it will be examined in this following section.
