Reinforced Concrete Frames are the most commonly adopted type of buildings in India. As the urbanization is at its peak there is unavailability of horizontal space resulting in increased cost of land and need for agricultural land, high-rise structures have become highly preferable in India. High-rise structures not only have to take up gravity loads but also lateral forces. Many important Indian cities fall under high risk seismic zones; hence strengthening of buildings for lateral forces is a very important. In this study the aim is to investigate the safe, effective and economical structural system between Tube in Tube system and Bundled tube system. The ETABS models of Tube in Tube and Bundled tube system which is G+20+Terrace storey, are considered for analysis. The modeling and analysis of the building has been done by using structure analysis tool ETABS2018.both the building models are subjected to gravity as well as seismic loading, and analyze by using Equivalent static and Response spectrum analysis method. The results are compare and summarize on the basis of different parameters like lateral story displacement, base shear, storey drift, time period and shear lag.The aim of present study is to compare performance of high-rise structures with Tube in Tube system and Bundled tube system against lateral loading. Both system are designed by using Indian standard codes and Special Publication of Handbooks by Bureau of Indian Standards
