Highway bridges in seismically active regions are often subjected to multiple earthquakes, including multiple main shocks during their service. Repeated seismic events result in reduced structural capacity and may lead to bridge collapse, causing disruption in the normal service. Serious earthquake events cause damage of the elements, with different damage level, even causing them to collapse. It is very important to save the damaged or weakened structures by emergency supporting or/and later strengthening, and to perform rehabilitation of their seismic resistance. The methods of evaluation of seismic resistance of damaged elements and structures are discussed in this paper. After evaluation of the damage degree and determination of the required demands and available seismic resistance of structures, redesign must be performed. Also, the method of rehabilitation of the elements and entire damaged bridge structures are analysed, including both traditional and advanced techniques. The fo...cus of this paper is on reinforced concrete (RC) bridges. Post-earthquake assessment and analysis of the seismic performance of the bridges are analysed. Review and comparison of the international Code provisions related to topic are discussed as well. Criteria for the choice of structural interventions are discussed, as well.
