The aim of this paper is to investigate the change of stiffness of concrete railway bridge subjected to cyclic loading since cyclic loading affects several types of concrete structures during their service life. Its greatest impact can be seen on bridges, which are subjected to enormous loads from passenger of freight traffic in terms of weight as well as frequency. A railway bridge was chosen for application in order to simplify the task, as the trains are represented by uniformly distributed load at a specific location defined by the track. In this analysis, only the changes in concrete were considered. The reduced stiffness values were placed in to the calculation model following the standard staggered algorithm scheme. This application provided a base for drawing conclusions regarding the used crosssection of the bridge deck.
