Abstract
Retrofitting is to add something that did not have it when manufactured. This needs to improve the performance of building. The premature deterioration of structure is an economic burden not only on owners but also to the municipalities’ and nation as a whole. Over a period, as these structures become older, we find in them certain degradation or deterioration with resultant distress manifested in the form of cracking, splitting, delaminating, corrosion, etc. The retrofitting design of building presented in this paper is based on IS 1893 (Part-I)-2002 and IS 13920:1993. Main objective of the paper is to increase the height of existing building (i.e., G + 7 to G + 12) and providing the survivability functionality by different retrofitting techniques like additional shear wall and column jacketing. Also, comparing the stability of building in both case through analysis and adopting the suitable technique is to improve the performance of building after vertical expansion of building height. The sections of main structural member column, beam, and slab have been done assumed based on previous experience. A comparative study of the results obtained from analysis has been made in terms of story displacement, story drift, and base shear. The designed models were again analyzed, and results were compared in terms of different criteria.
