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.
