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 ...

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 ...

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, ...

Soil structure interaction effects on the resonant response of railway bridges under high-speed traffic
(Taylor & Francis, 2015)
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 ...

Scoping assessment of building vibration induced by railway traffic
(Elsevier, 2017-02)
This work presents a scoping model to predict ground-borne railway vibration levels within buildings considering soil-structure interaction (SSI). It can predict the response of arbitrarily complex buildings in a fraction ...

A 3D time domain numerical model based on half-space Green's function for soil-structure interaction analysis
(Springer, 2014)
This paper presents a numerical method based on a three dimensional boundary element-finite element (BEM- FEM) coupled formulation in the time domain. The proposed model allows studying soil-structure interaction problems. ...

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 ...

Design, tuning and in-field validation of energy harvesters for railway bridges
(Elsevier, 2024-02)
Energy harvesters are a promising technology for powering infrastructure condition monitoring systems without batteries. When deployed on railway bridges they are typically tuned to the bridge’s natural frequency, however ...
