Earthquakes are the disturbances which occur deep inside the earth's crust they are felt in the form of trembling of earth, jolts, movements and with less or more destructive phase. Although true cause of earthquake is not so easy to determine but most fortunate part is that can be predicted to very much extent. In some cases they are not yet possible to forecast, they usually come without warnings. Which make it a matter of discussion, every year it affects human life with large scale of destruction which brings to the concern of many researchers to minimize its consequences. India is country which has seen devastating effects of earthquakes from pasts. It has many weak zones which are more prominent under its influence. As it is said life never stops many attempts are ongoing to overcome heavy risk which are making it boon to fight such natural activities. We know that development is an ongoing process which is unaware of such activities which greatly affects the infrastructure of a country causing huge economic losses. Tall buildings are standing globally all over the world. What if, if such tall structure with complex designs and irregularities such as irregular plan, asymmetric structure, Floating Columns, balconies, projections etc. hits an earthquake, it will abolish its existence. Therefore, it's very necessary to safeguard human life and property which is a primitive step. From there comes the methods to control. Various ways are there to stop drifts, displacement and minimizing shear values. Variety of static and dynamics method are there to study behavior of structure and conclude most preferable results. One such method is Base-isolation is a very fast-growing technique to isolate a building from ground accelerations and to restrict the structures against objectionable lateral forces. The study uses a software method of dynamically analyzing a multi-storey modal structure as per Indian standards to know how much effective a base isolation method is when used in high seismic zone V.
