In the present study, a new method is proposed to analyse dynamic responses of the bridge subjected to a moving vehicle. Analysing the vehicle-bridge interaction system is useful for moving load identification and bridge structural damage detection. In this study, the algorithm based on explicit form of Newmark-β is proposed for dynamic analysis of the vehicle-bridge system. A three-span continuous bridge is used as a numerical example to investigate the efficiency of the proposed method and the results are compared with the existing results by the conventional state-space method. From the results, the proposed method is reliable and efficient for the vehicle-bridge interaction analysis.
