Abstract
Earthquakes are a huge concern for structures; causing losses of peoples lives, damages and collapse of homes. The main objective of the present study is to analyze and strengthen an existing old building by using proper and innovative retrofitting techniques and collected data from previous studies. The selected building is a two-storey of Backward class Boys Hostel in Akola consists of prefabricated concrete. The present study evaluates the performance of G+1 hostel building using equivalent seismic analysis of an existing building. In the next step the study evaluates the performance of the selected building for an additional floor. It is observed that the present building is inadequate to withstand the seismic loading for an additional building construction. The column member sizes failed on the addition of an extra storey and hence objective of the study is to develop technique to protect the existing structure. The study recommends jacketing of failed column members by increasing the column sizes and reinforcement requirement of the modified structure. The study also noted that the provided member sizes and reinforcement are sufficient to withstand the load of an additional two storey floors to meet the requirement of the occupancy at the hostel building.
