Review on Seismic Retrofitting of existing buildings

Esmaeil Asadzadeh


Existing buildings are designed according to the relevant codes and standards for pre-defined loads. Since the loads are not certain, building standards use statistical data to define them. Therefore, during the design some loading conditions may not be considered sufficiently.  Occurrence of some hazards such as, earthquake, extreme winds, flood, impact of vehicle, missile and explosion may be different during the lifetime of the buildings that has not been considered during the design. To withstand these extreme situations and fulfill the upgraded building codes’ requirements and reduce the construction cost, retrofitting of the existing buildings are the best solution. The present paper reviews the most recent methods and techniques applied for retrofitting of the concrete buildings.
