A Comparative Study of Design and Techniques for Retrofitting an Existing Structure by Cost-Benefit Analysis

Abstract

Retrofitting of any given structure is done to improve its strength and performance. In most scenarios, retrofitting is done to improve seismic resilience and performance, however in this investigation retrofitting techniques are utilized to change the functional use of a structure, to be more precise, the agenda is to transform a commercial 10 storey structure into a data center building. In order to encompass the additional load parameters, instead of complete reconstruction, retrofitting solutions are to be adopted, which reduces cost, labor and is very energy and environment conscious. The said structure was modelled using the E-Tabs software, with appropriate load parameters. Furthermore, the altered load parameters for the data center would likewise be examined to understand the extent of failure and would help in indicating the appropriate retrofitting solution to ameliorate the situation. In addition to the implementation of retrofitting strategies, we devised a small statistical prototype (Cost Benefit Analysis) which helped us to elucidate the need for a conventional approach. This project is cutting edge in the sense that a sustainable approach in the construction industry is sought to, looking at the need for energy efficiency.
