Abstract

The earthquake that occurred in Gujarat in 2001 and the earthquake that occurred in Kashmir in 2005 have brought awareness to the danger that earthquakes pose to buildings all over the country. There is a wealth of information available on the evaluation of multi-story buildings for seismic activity that makes use of nonlinear static (pushover) analysis. In spite of the fact that bridges are among the most significant constructions in any nation, there hasn’t been a lot of research done on how to analyse them for earthquakes. There are no comprehensive recommendations available at this time to assist structural engineers in the process of evaluating old bridges and coming up with design and repair plans. As a means of finding a solution to this issue, The goal of this research work  to use an existing RC bridge as a case study for a nonlinear static (pushover) analysis. Bridges move in a different way than structures do because they move horizontally and have two fixed ends. From the three-dimensional model, you can see that the bridge is made in several different ways. More people than ever before are taking part in the higher modes. Because bridges are so complicated, it may not be accurate to do a pushover analysis with only one load pattern. Analysis of the effects of soil-structure interaction on short-span RC bridges
