Retrofitting of Railway Bridge by using Method of Concrete Jacketing to the Pier and Abutment–A Case Study

The objective of this paper is to analytically investigate the influence of core preloading on the strength of jacketed R/C bridge pier sections and abutment. The objective of this task was to collect and review information on the current state-of-the-art for seismically upgrading vulnerable concrete bridge columns. The seismic weakness of such bridges was assessed through local and global response quantities. The retrofitting scheme adopted to enhance the earthquake, in the case study of Railway Bridge the concrete jacketing of all piers and abutments. And steel girder replaced by prestressed concrete girder
