In this paper, asynchronous and stochastic dynamic analyses of a cable-stayed bridge are carried out using the finite element method. The Jindo Bridge, constructed in South Korea, is chosen as a numerical example. In the asynchronous dynamic analysis, various wave velocities are used for the travelling ground motion. Displacements and internal effects are obtained using both methods, and compared with each other. It is observed that the velocity of the ground motion greatly influences the response of the Bridge.
