The dynamic behaviour of short simply-supported railway bridges under convoy circulations
and, especially, the effect of soil structure interaction (SSI) in the maximum
expectable deck transverse response is the aim of this study. These structures due to
their usually light weight may experience excessively high acceleration levels under
resonant conditions. In order to approach this wave propagation problem, a coupled
three-dimensional Boundary Element-Finite Element model formulated in the time
domain is used to reproduce the soil and structural behaviour, respectively. As the
resonant phenomenon in this application is highly influenced by the free vibration response
of the deck, a sensitivity analysis is designed in order to first analyse how SSI
affects the free vibration response of beams under the circulation of a single moving
load in a wide range of velocities. A subset of beam bridges is defined considering
span lengths ranging from 12.5 to 25 m, and fundamental frequencies covering associated
typologies. A single soil layer is considered with shear wave velocities ranging
from 150 to 365 m/s. From the single load free vibration parametric analysis conclusions
are derived regarding the conditions of maximum free vibration and cancellation
of the response. These conclusions are used afterwards to justify how resonant amplitudes
of the bridge under the circulation of railway convoys are affected by the soil
properties, leading to substantially amplified responses or to almost cancelled ones,
and numerical examples are included to show the aforementioned situations [-]
