Abstract: A building needs to be able to withstand considerable ground vibrations during construction or operation in order to be deemed earthquake-resistant. However, ground motions have a particular effect on structure reactions. Time-history analysis is effective for buildings that are subject to large ground vibrations. Stepwise integration of the pushover analysis of a multi-degree-of-freedom system (MDOF) in the time domain is used to illustrate a structure's response. This method is advantageous even if it takes a lot of time. In order to speed up the design and assessment of seismic structures, the pushover analysis was developed.Pushover study indicates that during seismic events, structures vibrate mostly in the lower or early modes. The multi-DOF system is then reduced to a single-DOF system using the characteristics revealed by its nonlinear static analysis. After that, a response spectrum analysis is performed on the ESDOF system using either nonlinear time history analysis, damped analysis, or constant-ductility analysis. Modal links are used to translate ESDOF seismic needs into MDOF seismic requirements.A model was created to show the overall consequences of the RCC frame building. In seismic zone II, four G+11 concrete planar frames with four bays oriented in X and Y were built in compliance with Indian regulations. There are five loading scenarios for every frame. Pushover analysis evaluates frames with different elevational anomalies but the same loading conditions. Frame after frame, the results are different. Each frame's capacity spectrum and pushover curve between base shear and displacement are calculated and evaluated. At seismic zone II stress, STAAD was utilized to analyze RCC frame non-linear response. To weight parameters, utilize Pro v8i. Infill walls and bare frames were compared
