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 ...

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 ...

Experimental and numerical evaluation of the wind load on the 516 Arouca pedestrian suspension bridge
(Elsevier B.V., 2022-01)
The present work analyses the wind load effects on the 516 Arouca bridge, the world's longest pedestrian suspension bridge in 2020. Computational fluid dynamics (CFD) was used to model a range of wind angles of attack ...

Numerical analysis of the crack paths produced by fibre–matrix interface failure in cross-ply LFRP laminates
(Elsevier, 2022-03)
The so-called matrix failure, also named inter-fibre failure, is one of the main failure mechanisms in long fibre reinforced polymers (LFRPs). This mechanism is characterized by the debonding of some fibres when transverse ...

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 ...

A multiscale data-driven approach for bone tissue biomechanics
(Elsevier, 2020-08)
The data-driven methodology with application to continuum mechanics relies upon two main pillars: (i) experimental characterization of stress–strain pairs associated to different loading states, and (ii) numerical elaboration ...
