The structural stability of railway viaduct as well as the passenger safety during the earthquakes has been a concern for many engineers recently. Conventionally, the design of railway viaduct design does not account complex interaction between soil and sub-structure. Vibrations induced in railway viaducts due to seismic excitations become eminent under resonance conditions and tend to be either attenuated or amplified by the soil medium. This paper presents a parametric study to investigate the static and dynamic structural response in terms of displacements and vibrations of railway viaduct; with and without soil-structure interaction.
