Infill walls have been widely used in RC structure but they are not included in the design. But
it has its own strength and stiffness and hence increases same of overall structure. This paper
presents an analysis on performance-based seismic evaluation of G+20RCframe, using Nonlinear
Static Pushover analysis with SAP2000v14software for three different models i.e.,
Model-1:(RC bare frame), Model-2:(RC frame with MI wall (Soft storey)) and Model-3: (RC
frame with MI wall and SW for lift (Soft storey)). The investigation is carried out on
formation of hinges, base shear, drift, pushover curve and displacement occurred in frame
structure as per IS 1893-2002 for Zone III.
