An integrated coupling element considering wheel-rail interface for analyzing the
dynamic responses of vehicle-rail-bridge interaction system with a non-uniform continuous bridge
is presented. The governing equations of the interaction system are established first, and the
solution procedure and assembly method of the coupling element are demonstrated. Finally, the
accuracy, efficiency and function of the integrated coupling element are tested using two numerical
examples. The influences of different combinations of rail and bridge element length in the coupling
element on the solution are investigated, and the effects of different rail irregularities on the
dynamic responses are discussed.
