In developing countries like India some cities are overcrowded with population and count is increasing day by day, therefore the demand for high rise buildings is increased. As height of building increases lateral loads such as wind and earthquake must be considered along with gravity loads. As compared to vertical loading, lateral load effect on a building increases exponentially with increase in its height. Engineers have developed several new framing schemes for tall buildings in order to minimize the effect of lateral loads. Present work aims to study and compare seismic response of structures subjected to non-linear dynamic analysis. For this study framed structure, framed tube structure and tube-in-tube structure are considered. Results of analysis are compared in terms of structural parameters like maximum lateral displacement, maximum storey drift, base shear and shear lag. ETABS 2016 the structural software for building analysis and design is used for analysis.
