Retrofitting of Existing Building by Concrete Jacketing
Abstract
For analysis and design check of buildings, ETABS v15 has been used. Beams and Columns have been modelled as frame elements. Beam and column sizes have been taken as per the existing values. Retrofitted sections will be suggested and modelled on a utility called Section Designer in ETABS based on Column-Beam Capacity Ratio. Nonlinear default hinges have been applied to beams and columns as per ASCE 41 document (FEMA 356). For nonlinear time history analysis, spectrum compatible ground motions have been used. The final conclusion will be suggesting the buildings performance levels corresponding to a certain retrofit scheme.
