The tube in tube structures is the innovative and fresh concept in the tubular structures. The tube in tube structures is especially suitable for all tall buildings. Bracing and shear wall are best concepts in a structure analysis of seismic force-resisting systems. Bracing and shear wall provide as additional lateral resistance against the lateral force. In the proposed study, tube structures of different heights have been considered. Bracing has been installed at corner along the structure's height and without bracing also meanwhile, shear wall provides in central core. Soil structure interaction (SSI) has also been taken into account. The parameters, such as maximum Story displacement, base shear, story drift, and story shear have also been studied. A tube-in-tube structure has been modelled in ETABS 2018.
