Bridges for the high speed railway lines in Spain. Design criteria and case studies

ABSTRACT: This article synthesises the design criteria of the new bridges designed for the High-Speed Railway (HSR) Lines in Spain, remarking the most relevant aspects. The contribution reports several case studies, illustrating the structural behaviour and construction procedure, based on the experience of the author in the design of more than 13.5 km of HSR bridges, including the two first steel viaducts on the line Madrid-Barcelona-French Border.
