In this paper, a procedure of nonlinear analysis of the cable-stayed bridge was developed based on the nonlinear theory of structures using the finite element method, in which the vehicle-bridge interaction element based on the concept of dynamic condensation is used. The influence of vehicles on the response of the cable-stayed bridge is studied by employing the spung mass model and the bridge model with and without considering cable vibration modes.
