Abstract:
Earthquake is considered as a most vulnerable activity for buildings. In this study, the existing building is considered which was not designed by consideration of earthquake, so as a part of a safety this building will be analysed by considering earthquake load and a new design will be given for retrofitting. The traditional method of seismic retrofitting is reviewed and their weak points are identified. Modern method and philosophies of retrofitting and energy dissipation devices are reviewed. The presentation is illustrated by case studies of actual buildings where traditional and innovative retrofitting methods have been applied. RC Jacketing of structural member is most suitable method for strengthening of building. Retrofitting is used to increase the load carrying capacity, increasing the current structure's stiffness, strength and ductility. The construction would therefore lead in secure and stable structures.
