Earthquakes are known to produce one of the most destructive forces on the earth. It can causes loss of life and property and
economical loss of the country. Earthquake cannot be prevented, since it is unpredictable, but loss of life of people and
damage to the structures can be prevented if later is designed properly. Performance Based Design (PBD) of structure is the
modern approach to earthquake resistant design. PBD is applicable to design of new buildings or retrofit to existing
buildings. PBD defines various limit state of performance for the building and hence gives clearcut idea about its
performance under hazards that is considered.
Present study work is carry out the work on performance level of G+4 storey R.C.C. building using specified limit states as
per ATC-40 and Indian code. Analysis has been carried out using ETABS (version 9.5). Three analytical models are
considered in present study, namely, Bare Frame (i.e, w/o masonry infill wall), Frame with infill wall as membrane and
Frame with infill wall as strut. This paper includes the evaluation of pushover curve, capacity spectrum curve and
performance point for pushover analysis applied on G+4 storey R.C.C. building.
