| Abstract: | Based on the results of model tests, this article deals with the rain wind vibrations of stay cables, mainly from the aspect of theoretic analysis. A new two dimensional mechanical model is built and a possible mechanism is presented to explore the real reason of the rain wind vibrations of stay calbes. Furthermore, the effects of main parameters to the vibrations are discussed. |
