In this paper, the plate girder bridge is modeled as an orthotropic plate, and the vehicle is modeled as a group of loads moving on the orthotropic plate. Based on the Halmiton’s theory and modal superposition principle, the state\|space equation of the system is obtained. Three methods are used to solve the equation to obtain the vibration response of the plate girder bridge. The results obtained are then compared with the exact response calculated by the convolution integration method, and the relative error of displacements and strains are all less than 8%, which verifies that the three methods for solving the vibration response of the bridge are effective and time-saving.
