Abstract


.

The design and construction of the Almonte viaduct has been a challenge due to the exceptional dimensions of the arch, which exceeds due to the 384 m span all previous experience in railway arch bridges. The detailed design of the structure has required the development of complex calculation models, considering both geometrical and material non-linearity, as well as all the stages of the construction process. The specific design considerations of the high-speed railway viaducts have forced to perform additional checks that exceed the scope of the current regulations. This article includes different aspects of the conceptual and detailed design of the structure that are relevant for their interest.
