Two FE models to analyse the dynamic response of short span simply-supported oblique High-Speed railway bridges: comparison and experimental validation
(Elsevier, 2018-07)
In this paper the dynamic response of a particular type of high-speed railway bridge common in the Spanish railway system is analysed with the aim of evaluating the levels of vertical vibrations experienced at the platform. ...

A 2.5D time-frequency domain model for railway induced soil-building vibration due to railway defects
(Elsevier, 2019-05)
A new hybrid time-frequency modelling methodology is proposed to simulate the generation of railway vibration caused by singular defects (e.g. joints, switches, crossings), and its propagation through the track, soil and ...

A time domain analysis of train induced vibrations
(Techno-Press, 2012)
This paper is intended to show the robustness and capabilities of a coupled Boundary Element-Finite Element technique for the analysis of vibrations generated by high-speed trains under different geometrical, mechanical ...

Effect of the end cross beams on the railway induced vibrations of short girder bridges
(Elsevier, 2019-12-15)
This work is devoted to the analysis of the railway-induced vertical vibrations of simply-supported double track bridges composed by pre-stressed concrete girder decks. Despite the low torsional stiffness that this particular ...

On the formulation of a BEM in the Bézier–Bernstein space for the solution of Helmholtz equation
(Elsevier, 2019-10)
This paper proposes a novel boundary element approach formulated on the Bézier-Bernstein basis to yield a geometry-independent field approximation. The proposed method is geometrically based on both computer aid design ...

A novel 2.5D spectral approach for studying thin-walled waveguides with fluid-acoustic interaction
(Elsevier, 2018-07)
This paper presents a novel formulation of two spectral elements to study guided waves in coupled problems involving thin-walled structures and fluid-acoustic enclosures. The aim of the proposed work is the development of ...

Scoping assessment of free-field vibrations due to railway traffic
(Elsevier, 2018-11)
The number of railway lines both operational and under construction is growing rapidly, leading to an increase in the number of buildings adversely affected by ground-borne vibration (e.g. shaking and indoor noise). ...

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 ...
