A survey of methods and techniques used for Seismic retrofitting of RC buildings

It is a known fact that the Globe is facing a threat of natural disasters from time to time. With particular records based on earthquake occurrence, the consequences are loss of human lives and destruction of properties, which ultimately affects the natural economy. The occurrence of an earthquake cannot be predicted and prevented but the preparedness of the structures to resist earthquake forces become more important. Keeping the view of constant revision of the seismic zones in India, lack of proper design and detailing of structures against earthquake. Initiatives are being taken by a number of agencies in country towards reduction of seismic risk in existing building. In the past few decades, significant research effort, work over, have been dedicated to retrofitting of existing building and number of research papers and reports have been published. Still, the subject is in development stages and standardization of practice is a distant goal. In this paper comprehensive review of methods and techniques used for seismic retrofitting of RC buildings are discussed briefly. Finally, general concluding remarks are made along with possible future direction of research.
