Abstract: Earthquake-resistant design of structures is an innovative developments and trends which are coming up. High raised buildings are less resistant to seismic forces. The tube in tube structural system consists of an exterior framed tube with a central core tube which is connected by floor slabs, also known as hull and core overcomes this difficulty in an effective manner. An RCC pentagonal and hexagonal tube in tube structure is compared with conventional pentagonal and hexagonal structure is subjected to rigorous seismic analysis and is compared to infer the relative resistance to seismic loads. The analysis is performed systematically in STAAD.Pro. This analysis is carried out for different seismic zones (Zone II to Zone V). The results from the analysis ascertain the behaviour of tube in tube and conventional structure when subjected to earthquakes. From this study, we also establish the most vulnerable tube in tube structure against their conventional complements
