Abstract: The imperative of tall structure have been rapidly growing far and wide. However, one of the regular wonder which is delivered in earth covering that is shake. Length of seismic tremor within couple of minutes an enormous number of people lose their lives and structures in different parts of the world. Starting late structures are ending up being progressively thin and exposed to impact and along these lines hazardous in the midst of tremor, parallel unfaltering quality has reliably been a critical issue of structures especially in the reaches with high shake peril. Exactly when a tall building is subjected to parallel or torsional redirection under action of fluctuating sidelong loads, the consequent oscillatory advancement can incite a broad assortment of response in the building tenants from the smooth uneasiness to serious affliction. Hence flat robustness is genuine thought in the diagram of tall structures. In the present research we have used software ETABS as per Indian standards. The comparison has been carried out for 20-storey, 40-storey, 60-storey of (i) Bracing system (ii)Frame with shear band and outrigger trusses system (iii)Outtrigger system (iv)Diagrid systems and combinations in (v) Bracing and outtrigger system (vi)Out trigger and Diagrid system (vii) Diagrid and frame with shear band and outtrigger trusses (viii) Bare frame are studied here. The modelling are done to examine the effect of different cases along with different heights on seismic parameters like base shear, lateral displacement, lateral drifts. The study has been carried out for zone v. Static and dynamic methods are used to analyses the structural systems.

Keywords: structural systems, lateral displacement, storey drift, base shear
