The earthquakes in the Indian subcontinent have led to an increase in the seismic zoning factor over many
parts of the country. Also, ductility has become an issue for all building that was designed and detailed using earlier
versions of the codes. Under such circumstances, seismic qualification of building has become extremely important.
The structural engineering profession has been using the nonlinear static procedure (NSP) or pushover analysis.
Modeling for such analysis requires the determination of the nonlinear properties of each component in the structure,
quantified by strength and deformation capacities, which depend on the modeling assumptions. Pushover analysis is
carried out for either user-defined nonlinear hinge properties or default-hinge properties, available in some
programs based on the FEMA-356 and ATC-40 guidelines. This paper aims to evaluate the zone –IV selected
reinforced concrete building to conduct the non-linear static analysis (Pushover Analysis). The pushover analysis
shows the pushover curves, capacity spectrum, plastic hinges and performance level of the building. The non-linear
static analysis gives better understanding and more accurate seismic performance of buildings of the damage or
failure element.
