A transfer function method to predict building vibration and its application to railway defects
(Elsevier, 2020-01-30)
This work presents a simplified method to evaluate building shaking due to arbitrary base excitations, and an example application to railway problems. The model requires minimal computational effort and can be applied to ...

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. ...

On the vertical coupling effect of ballasted tracks in multi–span simply–supported railway bridges under operating conditions
(Taylor & Francis Group, 2022)
This contribution investigates the vertical coupling exerted by ballasted tracks on the vertical response of bridges composed either of (i) several successive simply-supported spans with weak coupling between them due to ...

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 ...

Dynamic load allowance of long-span modular steel bridges
(Elsevier, 2023-05)
Modular steel bridges are structures whose construction is based on regular prefabricated truss units. This presents several advantages, such as rapid and easy deployment, high adaptability to the terrain and reduced c ...

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 ...

Vibration serviceability assessment of the world's longest suspended footbridge in 2020
(Elsevier, 2022-10)
This paper investigates the vibrations induced by humans through in situ behaviour tests of the 516 Arouca footbridge (Portugal), the world's longest span in 2020 (516 m). The study consists of in situ experimental tests ...
