dc.description.abstract | A novel numerical methodology is presented to solve the dynamic response of railway
bridges under the passage of running trains, considering soil–structure interaction. It is
advantageous compared to alternative approaches because it permits, (i) consideration
of complex geometries for the bridge and foundations, (ii) simulation of stratifed soils,
and, (iii) solving the train-bridge dynamic problem at minimal computational cost. The
approach uses sub-structuring to split the problem into two coupled interaction problems:
the soil–foundation, and the soil–foundation–bridge systems. In the former, the foundation and surrounding soil are discretized with Finite Elements (FE), and padded with Perfectly Match Layers to avoid boundary refections. Considering this domain, the equivalent
frequency dependent dynamic stifness and damping characteristics of the soil–foundation
system are computed. For the second sub-system, the dynamic response of the structure
under railway trafc is computed using a FE model with spring and dashpot elements at
the support locations, which have the equivalent properties determined using the frst subsystem. This soil–foundation–bridge model is solved using complex modal superposition,
considering the equivalent dynamic stifness and damping of the soil–foundation corresponding to each natural frequency. The proposed approach is then validated using both
experimental measurements and an alternative Finite Element–Boundary Element (FE–
BE) methodology. A strong match is found and the results discussed | es |
