[EN] Currently most railway bridges in Australia require the replacement of the timber transoms that reside in the railway system. Composite steel and precast reinforced concrete transoms have been proposed as the replacement ...
[EN] This article addresses the dynamic behaviour of double track simply supported bridges of short to medium span lengths (10 m < L< 25 m) belonging to conventional railway lines. These structures are susceptible to ...

[EN] This paper deals with the application of Passive Control techniques to mitigate the excessive vibrations that short simply supported railway bridges may undergo under the circulation of High-Speed trains. A possible ...
[EN] In this paper, a closed-form approximate formula for estimating the maximum resonant response of beam bridges on viscoelastic supports (VS) under moving loads is proposed. The methodology is based on the discrete ...
The advent of high-speed railways has raised many concerns regarding the behaviour of bridges. Particularly, the analysis of the free vibrations generated by each load is of great interest because they can possibly accumulate ...
[EN] A significant number of railway bridges composed by simply-supported (SS) spans are present in existing railway lines. Special attention must be paid to short to medium span length structures, as they are prone to ...

[EN] In this paper, the dynamic performance of a certain kind of existing bridge under the action of highspeed
railway traffic is addressed. Short-to-medium-span simply supported structures are susceptible
to experiencing ...
