The dynamic response of base-isolated bridge with various isolators is presented. Bridge modal of 2-span of length 19.5 m and width of 12.16 m has been picked for the present study. Two models are used in this study, one is non-isolated railway bridge with ballastless slab track and another one is base-isolated railway bridge with ballastless slab track of base-isolated bridge with different HDRB. Isolators are designed by considering suitable soil type and site conditions. And, the properties of isolators are introduced between super structure and sub structure. Influence of the base isolator is studied, and both the models are analyzed for seismic response spectrum method in both horizontal directions. The influence of the HDRB in the dynamic behavior of the bridge is observed. Parametric studies are performed for different system configurations, isolation systems, and frequency ratios under torsional coupled and uncoiled conditions. The dynamic response of the base-isolated bridge varies significantly due to the disparity in the isolator properties.
