Description
In this paper, we used differential transform
method (DTM) to analyse free vibration of a railway bridge,
modelled as an orthotropic rectangular plate, supported by
Pasternak foundation. The effect of damping was considered.
The present method transformed the governing equation to its
algebraic form. Solution form to similar equation was adopted.
The results obtained are in agreement with the ones in
literature, and it shows that the technique introduced is easy to
apply to such differential equation governing the vibration of
such plates.
