SUSTAINABLE STRUCTURAL RETROFITTING OF RC BUILDING BY NON-LINEAR STATIC ANALYSIS

Most of the buildings are affected during the earthquake, as they are designed IS 456:2000 for the gravity loading. So, these buildings may not possess strength, ductility and stiffness. To strengthen these structures, Non-Linear static Pushover Analysis of the building is carried out before and after the retrofitting of the columns of the building in order to find out the effectiveness of the retrofitting. Different retrofitting techniques have been applied such as, Concrete Jacketing, Steel Jacketing and Composite Jacketing. Response Spectrum Method and Non-linear Pushover methods were used to analyse the building models and the results acquired have been compared. Conclusions were made depending on displacement, inter storey drifts, base shear, stiffness, axial load, shear force and moment on the columns.
