The advances in three-dimensional structural analysis and computing resources have allowed the efficient and safe design of taller structures. Tubular structures are common structural system for tall buildings over past few years. The tubular structures are of different types in which tube in tube structures are more suitable for high rise buildings. A tube in tube structure is formed by outer framed tube and inner core tube connected by floor slab. It is act like a huge tube (i.e. Peripheral tube) with a smaller tube (i.e., core tube) in middle of it. The load is transfer between these two tubes. In which a strong center tube of high strength concrete is the main load carrying structure. Presence of shear walls imparts a large stiffness to the lateral force resisting system of the RC building. One of the major parameters influencing the seismic behavior of shear wall frame buildings is the shear wall area ratio. Thus an analytical study is performed to evaluate the effect of Shear Wall Area to floor area ratio (SWA/FA %) on the seismic behavior of multistoried RC structures. For this purpose, 30 stories with SWA/FA % is considered.Then, the behavior of these building models under earthquake loading is examined by carrying out Static and Response Spectrum Analysis using structural analysis software E-TABS. Static and Response Spectrum Analysis is done according to seismic code IS 1893:2002.
