3D analysis of railway induced vibrations on skew girder bridges including ballast track-bridge interaction effects
Elsevier (2023-01-11)This work is devoted to the analysis of the vibratory response of High-Speed (HS) multi-track railway bridges composed by simply-supported spans. In particular, it aims to investigate the influence of three geometrical ... -
Analysis of the Effect of Soil-Structure Interaction on the Response of Railway Bridges using Boundary Element - Finite Element Methods
Civil-Comp Press (2016)The dynamic behaviour of short simply-supported railway bridges under convoy circulations and, especially, the effect of soil structure interaction (SSI) in the maximum expectable deck transverse response is the aim of ... -
Ballast shear effects on the dynamic response of railway bridges
Elsevier (2022-10-09)Single-track railway bridges are susceptible of experiencing high levels of vertical acceleration on the deck that may be dangerously accentuated at resonance. This is especially critical for short-to-medium span simply ... -
Ballasted track interaction effects in railway bridges with simply-supported spans composed by adjacent twin single-track decks
Elsevier (2021-09-08)This paper is devoted to track-bridge interaction phenomena in railway bridges of short simply-supported (SS) spans composed by ballasted tracks. These structures may experience high vertical acceleration levels under ... -
Energy harvesting analysis in railway bridges: an approach based on modal decomposition
Elsevier (2021)In this paper the authors investigate the energy harvesting in railway bridges and analyse the performance under different operational conditions. An approximation based on modal superposition is proposed for the computation ... -
Influence of track modelling in modal parameters of railway bridges composed by single-track adjacent decks
Universitat Politècnica de València (2022-05-01)A significant number of railway bridges composed by simply-supported (SS) spans are present in existing railway lines. Special attention must be paid to short to medium span length structures, as they are prone to ... -
Maximum resonance and cancellation phenomena in orthotropic plates traversed by moving loads: Application to railway bridges
Elsevier (2019-11-09)The vibrational response of railway bridges is an issue of main concern, especially since the advent of High-Speed traffic. In the case of short-to-medium lengths and simply-supported spans excessive transverse acceleration ... -
Optimal design and application of 3D printed energy harvesting devices for railway bridges
CRC Press (2023-06-28)In this paper, the authors investigate energy harvesting on railway bridges. The tuning frequency for the optimal design of cantilever based 3D printed energy harvesters is studied. An analytical model to represent the ... -
Soil–structure interaction effects on the resonant response of railway bridges under high-speed traffic
Taylor & Francis (2015-08)In the present contribution, the dynamic behaviour of beams traversed by moving loads including soil–structure interaction (SSI) is investigated. The main application of the study is to analyse the effects of SSI on the ...
