Now, a day’s tall structure and building are mostly need for human being in urban areas. and tall structure are mostly build with central core (comprising of shear wall or braced frame) at the center of building. The central core consumes a large part of area of floor space and so that less space are profitable for use for residential and commercial use of building. At some height of building the central core would not be sufficient to keep structure stable. Now a day’s seismic resistant design is mostly used for tall structure and outrigger system to resist lateral force of building, so that it needs to be connected with outrigger system. From Analytical study, we will be observed that among various configuration, outrigger system offers better resistance to applied lateral loads. And so that we will analysis the structure without outrigger (shear wall or braced frame) and outrigger system and study the behaviour of tall building. The three sets of outrigger models, same models but at different height of building are subjected to earthquake load and analysis for G+29 storey tall reinforced building and compared to find storey displacement, storey drift, base shear. The dynamic analysis is carried out based on Indian standard code IS-875(PART 3), Earthquake load using Response spectrum method by IS-1893 PART1(2016). the analysis will be done for zone 3 and zone 5, The location of outrigger will be used for three optimum position G+9 storey height, G+19 storey height, and G+29 storey height of same building. ETABS computer software will be used for analysis.
