Identificación Dinámica de Elementos de Hormigón Armado Fisurados Reforzados Externamente con Fibras de Carbono
(Asociación Española de Ingeniería Mecánica, 2004)
Las estructuras de hormigón armado pueden sufrir daños a lo largo de su vida causados, por ejemplo, por cargas subestimadas o imprevistas o condiciones medioambientales. Una técnica usada para reparar estructuras de ...

Identificación de daños en estructuras a partir de su respuesta dinámica
(Asociación Española de ingeniería Mecánica, 2008)
La presencia de daños en estructuras puede deberse a multitud de causas. Por ejemplo, debido a causas accidentales que excedieron aquellas para las cuales fueron diseñadas las estructuras o simplemente porque éstas han ...

3D analysis of railway induced vibrations on skew girder bridges including ballast track–bridge interaction effects
(Elsevier, 2023-03)
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 ...

Vibrations induced by HST passage on ballast and non-ballast tracks
(Elsevier, 2010)
The use of ballastless slab track is significantly increasing in HST line technology. This development is due to some structural and operational advantages over ballasted track. In addition, floating slab tracks can be ...

Fast simulation of railway bridge dynamics accounting for soil–structure interaction
(Springer, 2021-08)
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 ...

The effect of rolling stock characteristics on differential railway track settlement: An engineering-economic model
(Elsevier, 2022-11)
Railway track geometry deteriorates under repeated train loading. When linespeed is increased or new rolling-stock is introduced this can alter the future rate of change of differential settlement and track geometry. ...

Wavelet and Lipschitz exponent based damage identification method for beams using mode shapes
(Elsevier, 2022)
This paper presents a damage identification method for beam-type structures based on the wavelet analysis. The damage location is predicted by a Damage Locating Index (DLI) based on a combined identification of local maxima ...

Effect of soil properties on the dynamic response of simply-supported bridges under railway traffic through coupled boundary element-finite element analyses
(Elsevier, 2018-09)
Railway induced vibrations on short-to-medium span simply-supported (SS) bridges is addressed in this contribution. Such structures may experience high levels of vertical acceleration at the platform, leading to adverse ...

Ballast shear effects on the dynamic response of railway bridges
(Elsevier, 2022-12-01)
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 ...
