The normal component of recorded near-fault ground motions is used as input ground motions. The selected bridge consists of multi-span continuous deck supported on piers and abutments. In the modeling of the bridge, the deck is considered as rigid whereas the piers are assumed as flexible. The friction coefficient of the VCFPS is assumed to be independent of the relative velocity at the sliding interface. The governing equations of motion of seismically isolated bridge are solved in the incremental form by employing Newmark’s step-by-step method assuming linear variation of acceleration over small time interval. In addition, comparison is made between the response of bridge isolated with VCFPS and FPS in order to measure the effectiveness of VCFPS. Furthermore, a parametric study has been carried out to critically examine the influence of important parameters on the seismic response of bridge isolated with VCFPS. From the above investigations, it is concluded that under near-fault ground motions, the VCFPS is quite effective for controlling the seismic response of bridge within the desirable range.
