A 2.5D coupled FE–BE methodology for the dynamic interaction between longitudinally invariant structures and a layered halfspace
(Elsevier, 2010-04)
This paper presents a general 2.5D coupled finite element–boundary element methodology for the computation of the dynamic interaction between a layered soil and structures with a longitudinally invariant geometry, such as ...

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 ...

3D printed energy harvesters for railway bridges-Design optimisation
(Elsevier, 2023-05)
This paper investigates the optimal design of 3D printed energy harvesters for railway bridges. The type of harvester studied is a cantilever bimorph beam with a mass at the tip and a load resistance. These parameters are ...

Influencia de los anclajes en vigas de hormigón armado reforzadas con laminado de fibras de carbono
(Asociación española de ingeniería mecánica, 2004)
La resistencia a flexión de vigas de hormigón armado puede ser incrementada adhiriendo externamente láminas de fibras de carbono (CFRP) en la zona traccionada. En muchos casos, no se alcanza la resistencia última del ...

Modal identification of a pedestrian bridge by output-only analysis
(Society for Experimental Mechanics (SEM), 2005)
The modal parameters (natural frequencies, mode shapes and damping ratios) describe the dynamic properties of a mechanical system. The classical modal analysis, based on Frequency Response Function, require measurements ...

A 3D Numerical Mode for HST Induced Vibrations
(Multi-Science Publishing, 2010)
A general numerical model for the analysis of soil motion due to high-speed train passage and effects on nearby surface and underground structures is presented in this paper. In contrast to other existing approaches, ...
