Damage detection in beams from modal and wavelet analysis using a stationary roving mass and noise estimation
(Wiley, 2018-04)
This paper uses the Continuous Wavelet Transform Analysis on mode shapes for damage identification. The wavelet analysis is applied to the difference in the mode shapes between a healthy and a damaged state. The paper also ...

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 ...

Crack location in beams using wavelet analysis
(Scientific.Net, 2013)
Abstract: This paper applies a methodology for damage detection in beams proposed by the authors. The methodology is based on a continuous wavelet analysis of the difference of mode shapes between a damaged state and a ...

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 ...

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 ...

On the basic phenomenon of soil-structure interaction on the free vibration response of beams: application to railway bridges
(Elsevier, 2016)
The dynamic transverse response of beam type bridges under railway tra c is addressed in this contribution. In particular, how soil-structure interaction may a ect the critical or resonant speeds and the associated vibratory ...
