Design of The Two-Line Railway Bridge with the Longest Span in Slovakia

The bow-string bridge across river Vah has been designed on the main Slovak railway line. Total length of the bridge is almost 380 m, while the lengths of two main spans are 124,8 m. To analyze behaviour of the bridge, spatial transformation model were developed using FEM software. The Eurocodes were applied for all verification procedures. Bridge global analysis and verification of arches allowing for buckling are given in more detail. Design of atypical bearings and issues with fulfilment of deformation requirements are discussed as well.
