Performance of Tubular Structure under Seismic Excitation

Abstract

Advancement in the building construction technology and structural analysis the tall structures have been significantly increased due to over growing population and for land mark of country. The tall structures are more prone to lateral load. In this study different forms of tubular structure are used to resist the Earthquake forces. Tubular structures are made based on the idea that building is design to act like a hollow cylinder cantilever perpendicular to the grounds. The aim of this paper is to present the seismic performance of tubular structure with and without central core. The Framed tube system, Tube in tube system, Bundled tube system, Braced tube system and Moment resisting Frame was analyzed to draw the comparison on the basis of base shear, storey drift, time period and storey shear satisfying the structural codes- IS 456-2000, IS 1893(Part 1):2016 in E-TABs software by Response spectrum method.
