The influence of mass parameter of dynamic foundation on dynamic response of beam subjected to moving vehicles is studied in this paper. The foundation model is described including: elastic stiffness parameter of Winkler foundation, shear layer based on Pasternak model, damping viscous and mass density parameter characterized the influence of mass of the foundation on response of structures. Based on principle of dynamic balance and finite element method, the equation of motion of beam subjected to moving vehicles is derived and solved by numerical integration method in the time domain. The effects of characteristic parameters of foundation mass on dynamic behavior of beam are investigated detaily.
