The design of high-speed railway bridges comprises a set of demands, from safety
and serviceability aspects, to new types of equipment and construction solutions. In order to perform
an accurate and realistic evaluation of the corresponding dynamic behavior, adequate
analysis tools that take into account the complexity of the train-bridge system are required.
These computational tools must be based on efficient algorithms to allow for the completion of
detailed dynamic analyses in a reasonable amount of time. The classical methods of analysis
may be unsatisfactory in the evaluation of the dynamic effects of the train-bridge system and
fully assessment of the structural safety, track safety and passenger comfort. A direct and versatile
technique for the simulation of the train-bridge interaction was implemented in the FEMIX
code, which is a general purpose finite element computer program. The presented case study is
an application of the proposed formulation, which proved to be very accurate and efficient.
