Abstract: For a purpose to calculate the local vibrations of the stay cables in cable-stayed bridge under wind-induced gust, the time-domain modeling of wind-induced vibration is employed in this paper. The global vibration of bridge deck due to the Wind-induced gust response is calculated by using the rational function and multidimensional autoregressive process. The local vibrations of stay cables, which are subjected to time-varying displacement at the supports during global motions, are used. Furthermore, the response characteristics of local vibrations of stay cables under wind are discussed by using an existing cable-stayed bridge.
