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 ... -
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 ... -
On the vertical coupling effect of ballasted tracks in multi–span simply–supported railway bridges under operating conditions
Routledge (2022)This contribution investigates the vertical coupling exerted by ballasted tracks on the vertical response of bridges composed either of (i) several successive simply-supported spans with weak coupling between them due to ... -
Resonance-Based Procedure for Locating Failed Luminaires in AGL Systems
Institute of Electrical and Electronics Engineers (IEEE) (2017-08)Aeronautical ground lighting (AGL) systems provide a visual reference for aircraft during airport operations. Fast detection and location of failed luminaires is an important safety concern in AGL systems. In the event of ... -
La resonancia en la teoría crítica de Hartmut Rosa: una respuesta a los límites prácticos de la ética discursiva para las sociedades aceleradas
Universidad de Murcia (2023)En aras del universalismo y en contra del totalitarismo, la ética discursiva ha mostrado con Jürgen Habermas un déficit práctico al negar a la filosofía moral la posibilidad de reflexionar sobre las condiciones alienantes ... -
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 ... -
Study of Resonances in 1X25 kV AC Traction Systems With External Balancing Equipment
IEEE (2016-10)AC traction systems are 1 × 25 or 2 × 25 kV/50 Hz single-phase, nonlinear, time-varying loads that can cause power-quality problems, such as unbalanced or distorted voltages. To reduce unbalance, external balancing equipment ... -
La teoría crítica de la resonancia de Hartmut Rosa frente a la aceleración: ¿Más allá del paternalismo y del totalitarismo?
Disputatio Editions (2023-02-20)Con su teoría crítica de la resonancia, Hartmut Rosa ha propuesto las bases de un modelo para evaluar normativamente y afrontar en la práctica las consecuencias de la aceleración social y su inherente tendencia al crecimiento ... -
Wind power plant resonances
North Sea Conference & Journal LTD (2016-12)Onshore and offshore wind power plants comprising wind turbines equipped with power converters are increasing in number worldwide. Harmonic emissions in power converters distort currents and voltages, leading ...
