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 ...

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 ...

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 ...

Scoping assessment of free-field vibrations due to railway traffic
(Elsevier, 2018-11)
The number of railway lines both operational and under construction is growing rapidly, leading to an increase in the number of buildings adversely affected by ground-borne vibration (e.g. shaking and indoor noise). ...

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 ...

Fast simulation of railway bridge dynamics accounting for soil–structure interaction
(Springer, 2021-08)
A novel numerical methodology is presented to solve the dynamic response of railway bridges under the passage of running trains, considering soil–structure interaction. It is advantageous compared to alternative approaches ...

Scoping assessment of building vibration induced by railway traffic
(Elsevier, 2017-02)
This work presents a scoping model to predict ground-borne railway vibration levels within buildings considering soil-structure interaction (SSI). It can predict the response of arbitrarily complex buildings in a fraction ...

Design, tuning and in-field validation of energy harvesters for railway bridges
(Elsevier, 2024-02)
Energy harvesters are a promising technology for powering infrastructure condition monitoring systems without batteries. When deployed on railway bridges they are typically tuned to the bridge’s natural frequency, however ...

The effect of ballast moisture content and fouling index on railway track settlement
(Elsevier, 2024-03)
A primary function of railway ballast is to maintain vertical track geometry, however over time it becomes contaminated with fines which reduce its ability to free-drain. Then, in the presence of moisture, the individual ...
