Dynamic soil-structure interaction analysis of high-speed railway bridges : efficient modeling techniques and experimental testing

The work reported in this thesis presents a general overview of the resonant response of high-speed railway bridges considering soil-structure interaction. The study aims to identify the effect of the surrounding and underlying soil on the global stiffness and damping of the structural system. This may lead to better assumptions and more efficient numerical models for design. A simple and accurate analytical model for computing the dynamic characteristics of the fundamental bending mode of single span beam bridges on viscoelastic supports was proposed. This model was used to study the effect of the dynamic stiffness of the foundation on the modal parameters of railway beam bridges.
