A performance-based Analysis is aimed at controlling the structural damage based on precise estimations of proper response parameters. Performance-based seismic design explicitly evaluates how a building is likely to perform; given the potential hazard it is likely to experience, considering uncertainties inherent in the quantification of potential hazard and uncertainties in assessment of the actual building response. It is an iterative process that begins with the selection of performance objectives, followed by the development of a preliminary design, an assessment as to whether or not the design meets the performance objectives, and finally redesign and reassessment, if required, until the desired performance level is achieved. In this present study three new R.C.C buildings unsymmetrical in plan (L-shape) (designed according to IS 456:2000) is taken for analysis: 4, 8 and 20 storey to cover the broader spectrum of low rise, medium rise & high rise building construction. Different modelling issues were incorporated through six model for each building were; bare frame (without infill), having infill as membrane, replacing infill as an equivalent strut in previous model. The pushover analysis has been carried out using ETABS, a product of Computers and Structures International. Buildings located in Zone-III have been analyzed Comparative study made for bare frame (without infill), having infill as membrane, replacing infill as an equivalent strut. The results of analysis are compared in terms of Base Shear, Storey Displacement and Drift Ratio.
