Energy harvesting analysis in railway bridges: An approach based on modal decomposition
(Elsevier, 2021-04-10)
In this paper the authors investigate the energy harvesting in railway bridges and analyse the performance under different operational conditions. An approximation based on modal superposition is proposed for the computation ...

On the dynamic characterisation of railway bridges through experimental testing
(Elsevier, 2021-01-01)
This work is devoted to the experimental evaluation of the dynamic response of railway bridges with common typologies in short-to-medium span lengths. An extensive experimental campaign is performed in several railway ...

Quadrature rule for singular integrals in common engineering problems
(WiT Press, 2022)
This paper describes a general method to compute the boundary integral equation for common engineering problems. The proposed procedure consists of a new quadrature rule to evaluate singular and weakly singular integrals. ...

An accurate treatment of non-homogeneous boundary conditions for development of the BEM
(Elsevier, 2020-07)
This paper proposes an enhancement of the treatment of non-homogeneous boundary conditions to improve the boundary element method (BEM) formulation. The standard formulation is modified by introducing the boundary conditions ...

Wavelet analysis of static deflections for multiple damage identification in beams
(Elsevier, 2021-01-15)
Wavelet analysis can be used in local damage detection due to its ability of revealing discontinuities induced by damage in the displacement field. This paper focuses on the application of wavelet analysis to detect and ...

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 ...

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 ...

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 ...
