A comparative study of the structure with and without core was carried out which is based on linear analysis and non-linear static analysis of two prototype structural frame. The existing FEMA-356, ATC-1997a and the result from the previous research reports which were used in the analysis of the structure. This paper also aims at establishing comprehensive seismic design as well as characterizing earthquake response characteristics and failure mechanisms of structures through analytical investigations under large earthquake.To ensure the safety of the structure only shear wall technique has been widely used and not much has been done with respect of core structures. In this paper instead of shear wall, Concrete Core has been used;the displacement was calculated by default procedure and the yield of the structure in both the direction result in the development of plastic hinge under push over loads. The outcomes would lead to develop the most efficient and most economical frame which can withstand the major earthquake. It also lead to motivate advances in seismic design practice. The core provided within the structure resulted in the less lateral displacement and restricted the development of the plastic hinges at the initial stages hence making the design robust and acts as an energy dissipater.
