There has been an enormous research in the field of seismic performance of structures.The improvement in the performance is still a challenging task for researchers andengineers. Many strategies have been considered in this regard to achieve desirable result.Base isolation is considered to be the most popular method of protecting structuresagainst seismic actions. However, use of different dampers has also been a majorrevolution in improving the seismic action of buildings. This review article is intended toillustrate different techniques for improving the seismic performance of buildings andbridges. The study mainly emphasizes on the effect of different isolators and dampers inmitigating the damage of buildings and other civil infrastructures. Pertinent study in thereview explores the possible application of the devices towards effective utilization inbuildings, bridge piers and other structures.
