Monitoring the mechanical behaviour of the weather vanesculpture mounted atop Seville Cathedral’s Giralda Tower
(SAGE Publications, 2010)
This article presents the application of monitoring and detection of structural damage techniques to a historic monument. Seville cathedral’s famous bell tower ‘La Giralda’ is 96 m tall and is crowned with a large 16th ...

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 spectral approach to represent acoustic and elastic waveguides interaction on thin slab structures
(Elsevier, 2017)
In this paper, we propose a spectral element method (SEM) to study guided waves in coupled problems involving thin-walled structures and fluid-acoustic cavities. The numerical method is based on the subdomain decomposition ...

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 BEM based on the Bézier/Bernstein polynomial for acoustic waveguide modelization
(WIT Press, 2019)
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 aided design ...

Scoping prediction of ground and building vibrations induced by railway traffic.
(2019-06-21)
The research proposed in this Thesis approaches induced vibrations by railway traffic at the soil surface and buildings close to the track. It is proposed a scoping model to predict the vibration levels in the free-field ...

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 ...
