Abstract

Recent developments in the field of high speed rail have heightened the need for improving of railway bridges under the passage of high speed trains. However, little attention has been paid to influence of significant parameters playing a key role in dynamic behavior of such bridges. This paper seeks to fill such a gap by carrying out finite element (FE) analysis on an existing railway bridge. For this purpose, the railway bridge is simulated by finite element software, LUSAS. Eigen value and moving load analyses are carried out to obtain the natural frequencies as well as the displacement of the simulated model, respectively, under the axial load of train passage. Different values of damping ratios and Young’s modulus are employed in these analyses and the effects of them are demonstrated in this study.
