ABSTRACT
ABSTRACT: This work discusses the influence of some issues arising from the dynamic resonant response on the design of railway bridges. These issues are related to dynamic analysis methods, composition of trains, and type of bridges. The evaluation of different response magnitudes is also addressed, showing that for calculation of bending moments or support reactions a much larger number of modes is needed in the model. Finally, a case study is presented with dynamic calculations for a large three-dimensional model of a special bridge.
