The seismic evaluation for the damage caused by ground motion to existing bridges has attracted focus of structural engineers in recent years. It is the first step towards curbing loss of life and property. Most of the reinforced concrete bridges in India were designed as per previous building codes. Those codes seldom accounted for large seismic motions and were insufficient to sustain the seismic loads acting laterally. It is necessary to evaluate damages caused to already constructed bridges. In this paper nonlinear static (pushover) method is focused for performing seismic analysis of RCC Bridge. It is conceptually easier to understand and model and requires low time for computation. Major advancement in pushover analysis procedures is seen in last 10 years and it has led to its introduction to international codes/guidelines for seismic analysis. The pier are subjected to dead load, live load and seismic loading and designed as per IRC-6 2012. The study aimed to determine the seismic performance of the typical reinforced concrete bridge pier designed as per Indian codes with displacement based pushover analysis approach.
