Horizontally curved bridges are important in modern highway systems and those are the most viable option at complicated interchanges or river crossings where geometric restrictions and constraints of limited site space make extremely complicated the adoption of standard straight superstructures. It has been observed that in past earthquakes, most of the damages of the bridges occurred due to the failure of the bearings and substructure. Selection of isolation bearings for a curved bridge is a demanding task because of the complexity involved in curved bridges than straight bridges. In the present study, the responses of an isolated curved continuous bridge for seismic loading conditions are determined. Two types of isolation bearings viz. one elastomer-based bearing and other friction-based bearing have been considered and the efficacy of both has been investigated.
