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 ...

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 ...

Railway slab vs ballasted track: A comparison of track geometry degradation
(Elsevier, 2023-05-16)
Concrete slab railway tracks typically have higher initial capital costs yet lower operational costs in comparison to ballasted tracks. One reason for the elevated operational costs on ballasted lines is the need for more ...

3D analysis of railway induced vibrations on skew girder bridges including ballast track–bridge interaction effects
(Elsevier, 2023-03)
This work is devoted to the analysis of the vibratory response of High-Speed (HS) multi-track railway bridges composed by simply-supported spans. In particular, it aims to investigate the influence of three geometrical ...

Optimal design and application of 3D printed energy harvesting devices for railway bridges
(CRC Press, 2023)
In this paper, the authors investigate energy harvesting on railway bridges. The tuning frequency for the optimal design of cantilever based 3D printed energy harvesters is studied. An analytical model to represent the ...
