ABSTRACT: The railwaybridges, due to the passage of high speed trains, can sufferhigh resonance phenomena
that cause, for example, ballast instability, endangering the railway line. Therefore, the main goal of this paper
was to develop a simplified but efficient MATLAB model able to reproduce and analyze the dynamic response of
bridges to the passage of high speed trains, in order to obtain static (bending moments, shear ...
