DYNAMIC RESPONSE OF TALL BUILDING

Abstract

With India's developing economy, urbanization, and lack of horizontal space driving up the cost of land and the need for agricultural land, tall buildings have become very popular, particularly in urban areas. When it comes to tall structures, not only do they have to withstand gravity loads, but they also have to withstand lateral forces. Many prominent Indian cities are in high-risk seismic zones, and tall buildings are the most vulnerable to earthquake and wind damage. As a result, lateral force resisting elements of tall structures is a must criterion. In this study, the vulnerability of tall buildings has been discussed, which are prone to seismic and wind loading. Then the research work of various researchers has been highlighted to anticipatethe performance of tall structures due to wind and seismic loading. Codal provisions, including various clauses of IS 16700: 2017 “Criteria for Structural Safety of Tall Concrete Buildings”, have also been discussed as compared to multi-storeyed buildings. A 20-storey (Height 64.80 m) building has been modelled using ETABS 2018 version software and analyzed using different methods, namely, equivalent static method, response spectrum method, time history method, pushover analysis and wind analysis. Results obtained from various analysis methods have been discussed, and some parameters have also been compared.
