Design and Seismic Analysis of a Building
Concrete | 2020
Earthquakes are the most destructive natural phenomenon which causes massive destruction to a structure. Reports suggest that the two sources of mistakes that may expose a structure to danger are, (1) Ignoring how an earthquake affects a structure, and (2) Poor construction practices. A proper analysis has to be performed to ensure that a structure is earthquake resistant. This project comprises the study and design of a seismically resistant G+6 RCC building situated in a zone 3 region in India. The analysis is performed on the computer software Staad-Pro. Lastly, we look into the application of retrofitting techniques in existing buildings in order to make them earthquake resistant. The idea is to do a comparative study of the various methods to retrofit a structure, including base isolation and damping, taking into consideration the structural serviceability and functionality post-earthquake and present a general retrofitting plan. It is to be noted that while it is not possible to present a foolproof design, the order of priority would be firstly for the building to be strong enough so that people have time to evacuate in the scenario of an earthquake, second for the building to not collapse even if it undergoes certain structural damages (because they can be repaired) so that it does not lead to loss of life and finally to design a structure that undergoes minimum damage and can be repaired with minimal costs.
