A seismic behavior of RCC high rise structure with and without outrigger and belt truss system for different earthquake zones and type of soil

In the present era, there is more demand for high-rise buildings. The growing de- mand buildings brings new difficulties and comes up with safety precautions. With an increase in height of structure, its rigidity reduces, making it difficult to withstand earthquake wind effects, hence some preventative structural systems must be used. Some them are bracings, shear walls, outrig- ger belt truss etc. outrigger system investigated this study since most effective method skyscrapers. To prevent story drift rotational action core caused by seismic forces, external columns attached main inner or outer using beams, trusses at various floor levels. All that situated peripheral connected together elements a system. This investigates comparison behavior without system, all zones (zone II, III, IV V) different types soil (hard, medium, soft). carried out 40 response spectrum analysis. Analysis building ETABS 2018 software. results form responses like storey displacement, Storey drift, base studied. Results show provision reduces displacement structure. After analysis comparing provided combination perform better as compared only
