Structural analysis of a railway bridge using the FEM-DEM technique

The objectives of this work are focused on giving an answer to the problems presented in operation a railway bridge, using FEM-DEM numerical technique considering static and dynamic loads. purpose is find out existing breakage mechanisms bridge. From social aspect, there concern about possible collapse with corresponding economic loss eventually human losses; therefore, interest involvement study has repercussions not only repair that can be adopted but also revision calculation design aspects type works. developed by Zárate et al. [1,2] been validated various laboratory tests [3-5]. Due characteristics problem, used ideal tool structural behaviour bridge from point view. Considering reinforcing steel fundamental carry analysis, which why implementation reinforcement formulation described.
