A displacement finite element method for analyzing a beam on continuous elastic foundation is presented. A three-dimensional model which accounts for the effects of both the Filonenko-Borodich and Pastemak foundation models in a consistent and complete way is used. A variational principle is introduced with the slope field due to bending only and the displacement field approximated by independe...

in this paper effects of fractured sleepers on rail track vibration under moving wheelset have been investigated. two parallel rails of the track have been modeled as euler-bernoulli beams on elastic points as rail pads. also sleepers have been modeled as visco-elastic euler-bernoulli beams. it is assumed that, some sleepers under the rail track have been fractured and modeled by two beams. the...

Abstract A novel numerical methodology is presented to solve the dynamic response of railway bridges under passage running trains, considering soil–structure interaction. It advantageous compared alternative approaches because it permits, (i) consideration complex geometries for bridge and foundations, (ii) simulation stratified soils, and, (iii) solving train-bridge problem at minimal computat...
