Abstract—The buildings that were designed and constructed according to old codes may not satisfy the requirements of the presently used seismic codes and design practices. Therefore, it is crucial to reassess these buildings. Buildings, which were damaged in past earthquakes or the existing buildings which are deficient at resisting seismic forces need to be retrofitted for better performance. Seismic evaluation is a necessary step before the retrofitting procedure to identify the most vulnerable components of a building during an expected earthquake. The seismic rehabilitation process aims to correct these deficiencies by increasing strength, stiffness or deformation capacity, and improving connections. The present study deals with the seismic retrofitting of two structures located in diverse seismic zones i.e. New Delhi and Mexico City. Each structure was retrofitted under two different schemes and the results were compared to identify the better method of retrofitting.
