This paper deals with the study of behavior of RC frames design for gravity (GF) and earthquake load (EQF). Nonlinear push over analysis was done using SAP on the models (GF & EQF). The functioning of RC frame is estimated in terms of displacement, shear, and performance point and inters story drift. The results from push over analysis for GF and EQF are compared with each other. An approach of the performance level of a 2D frame (PBF) has been done by using the Deformation based earthquake design with the displacement required to be achieved for the performance level as specified in FEMA 356. Here the yield strength is calculated for the required target displacement and the PBF frame is redesign by strength based. Hinges are developed in the ground floor vertical member while carried out the seismic design and only in beams in EQF this represent the strong beam column weak beam concept is applied and inter-story drift is more in top floor for GF and almost similar in all the floors for EQF. Yield shear strength obtained is almost equal to that of the analysis for Performance based frame.
