High-speed train-induced ground motion and interaction with structures
(Elsevier, 2007)
A general numerical model for the analysis of soil motion due to high-speed train passage and effects on nearby surface and underground structures is presented in this paper. Soil, ballast and structures are represented ...

Dynamic study of the Barqueta cable-stayed Bridge
(Society for Experimental Mechanics (SEM), 2006)
A theoretical and experimental research work of the Barqueta cable-stayed bridge is described in this paper. The Barqueta Bridge, across Guadalquivir river, links the city of Seville with the Scientific Park Cartuja 93. ...

Modal identification of a pedestrian bridge by output-only analysis
(Society for Experimental Mechanics (SEM), 2005)
The modal parameters (natural frequencies, mode shapes and damping ratios) describe the dynamic properties of a mechanical system. The classical modal analysis, based on Frequency Response Function, require measurements ...

Analysis of ground motion due to moving surface loads induced by high-speed trains
(Elsevier, 2007-11)
A three-dimensional time domain boundary element (BE) approach for the analysis of soil vibrations induced by high-speed moving loads is presented in this paper. An attenuation law is included in the formulation. By doing ...

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 ...

Fully three-dimensional analysis of high-speed traintracksoil-structure dynamic interaction
(Elsevier, 2010)
In this paper, a general and fully three dimensional multi-body-finite element-boundary element model, formulated in the time domain to predict vibrations due to train passage at the vehicle, the track and the free field, ...

Cálculo del término no singular de tensiones en una grieta 3D mediante una integral independiente del dominio
(Grupo Español de Fractura, 2006)
El término no singular de tensiones, denominado también “T-stress”, es el término asociado al autovalor λ =1 en la serie desarrollada por Williams (1957) para el campo de tensiones lineal elástico cercano al vértice de ...

A 2.5D coupled FE-BE model for the prediction of railway induced vibrations
(Elsevier, 2010)
Ground vibrations induced by railway traffic at grade and in tunnels are often studied by means of two-and-half dimensional (2.5D) models that are based on a Fourier transform of the coordinate in the longitudinal direction ...

Induced vibrations due to high-speed trains: Córdoba-Málaga high speed line
(Sociedad Española de Acústica, 2007)
Numerical models to obtain ground vibrations induced by the passage of HST, based on finite element method and boundary element method, have been developed in the last years. A few models have been validated, comparing the ...
