There are numerous structural lateral systems used in high-rise building design such as shear frames, frames with shear core, framed tubes, tube and tube, super frames etc. Generally, the structural systems of tall buildings are considered to be two types. One is interior and the other one is exterior type. A system is categorized as an interior structure when the major parts of the lateral load resisting system are located within the interior of the building. Likewise, if the major parts of the lateral load resisting system are located at the building perimeter, the system is categorized as an exterior structure. In this study it is intended to model an advanced structural system which can be applied to buildings taller than the existing tallest building in the world. In this innovative concept, several parallel shear walls have been arranged in both directions and connected with beams and R.C. floor slabs. The shear walls are continuous down to the base to which they are rigidly attached to form vertical cantilevers. Their high in plane stiffness and strength make them well suited for bracing buildings up to about 278 stories. Fewer widely spaced gravity columns are arranged in the core area of the building to carry floor loads. Because of the absence of core bracing and of a large number of heavy interior columns, the net leasable area for such a building increases. Static and Dynamic analysis (Time History Analysis) has been carried out. The drift by static analysis is 1884 mm which is below the allowable limit of 2001.6mm (If considered H/500, where H is the height of the structure [9]). Also it is found by research that, when this structural arrangement is applied to around 830 meter tall structure with aspect ratio 9.8:1, no additional structural supporting system (like Outriggers, Perimeter Belts, Cross Bracing, Tuned Mass Dampers etc.) is required. This shear walls arrangement is applicable for the tall buildings of any height to avoid additional supports to resist the lateral forces while taking advantage of the creative approach of this unique concept.
