The primary requirement of humans on planet earth is food, clothing and shelter. Prehistoric men and women used to live on trees but steadily they started developing the shelters for protection against natural calamities like rains, cold etc. and also from attack against wild animals. Soon humans grew in knowledge and they started living together, forming communities to ensure additional security and man became a social animal. Now these communities developed and started exploding forming villages which later on transformed into cities and became the commercial centres of a region. Soon within these commercial centres, land for horizontal expansion became extinct. The social animal started expanding vertically constructing multi-storied structures. The present study focuses on 12 levelled multi-storey structure. The structures are considered to be located at various seismic zones. The Performance of the structure is found out by static nonlinear structure. Further, these structures are provided with seismic dampers. The Modelling and analysis are carried out using ETABS software. The performance of these structures is studied and compared using various parameters such as displacement, storey drift, base shear and time period. Along with these results performance of building is predicted based on demand capacity graphs. The results are extracted and conclusions are drawn.From the pushover analysis, the performance point is found out for all the models. And also, it found that, weakest junctions of the models. The Pushover analysis shows the models with dampers are having base shear than the models without damper. The increase in percentage of base shear is around 45%. The introduction of damper causes the improvement in lateral load carrying capacity by 45%. The base shear values are lesser for Zone II and highest for Zone V. There is a linear increase in base shear values for increase in severity of zones. From the pushover analysis base shear, it is noticed that all the models are having lesser base shear values in case of equivalent static analysis than pushover analysis except Model type A4. This shows that, the model Type A4 is UNSAFE. The models can be made SAFE by introducing Dampers as in Models Type B4.
