On the basic phenomenon of soil-structure interaction on the free vibration response of beams: application to railway bridges
(Elsevier, 2016)
The dynamic transverse response of beam type bridges under railway tra c is addressed in this contribution. In particular, how soil-structure interaction may a ect the critical or resonant speeds and the associated vibratory ...

Acoustic waves scattered by elastic waveguides using a spectral approach with a 2.5D coupled boundary-finite element method
(Elsevier, 2019-09)
This work presents a two-and-a-half dimensional (2.5D) spectral formulation based on the finite element method (FEM) and the boundary element method (BEM) to study wave propagation in acoustic and elastic waveguides. The ...

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 ...

Dynamic characterisation of wind turbine towers account for a monopile foundation and different soil conditions
(Taylor & Francis (Routledge), 2017)
The response of wind turbines is induced by dynamic loads such as wind, transient and cyclic loads, and also extreme loads such as earthquakes. Thus, the structural design requires an accurate evaluation of the modal ...
