A 3D Numerical Mode for HST Induced Vibrations
(Multi-Science Publishing, 2010)
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. In contrast to other existing approaches, ...

3D non-linear time domain FEM-BEM approach to soil-structure interaction problems
(Elsevier, 2013)
Dynamic soil-structure interaction is concerned with the study of structures supported on flexible soils and subjected to dynamic actions. Methods combining the finite element method (FEM) and the boundary element method ...

Identificación dinámica de puentes de Sevilla mediante sus respuestas a cargas de servicio
(Escuela Técnica Superior de Ingenieros Industriales, Universidad de Castilla La Mancha, 2010)
En los últimos años se han construido en Sevilla varios puentes de diseño singular, suficientemente rígidos para soportar sus cargas de servicio, pero con un compartimiento dinámico que, en algunas ocasiones, alerta a los ...

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, ...

Modelling of acoustic and elastic wave propagation from underground structures using a 2.5D BEM-FEM approach
(Elsevier, 2017-03)
This paper presents a numerical method based on a two-and-a-half dimensional (2.5D) boundary element-finite element (BEM-FEM) coupled formulation to study noise and vibration from underground structures. The proposed model ...
