Abstract:
India is a developing country with a variety of building practices and social and economic
structure, which needs to evolve its own strategies for seismic hazard evaluation. The last decade
has pointed to our shortcoming in risk reduction programmes, during the few damaging
earthquakes. Due to this earthquake alone in India there was immense loss of life and property.
After this painful loss attention is now being given to the evaluation of the adequacy of strength
in structures to resist strong ground motions. After Bhuj earthquake IS-1893 was revised and
published in the year 2002, before this incident it was revised in 1984. The code was first
published in 1962 as ‘Recommendations for Earthquake Resistant Design of Structure’. The
main reason for the loss of life and property was inadequacy of knowledge of behavior of
structures during ground motions. The vulnerability of the structures against seismic activity
must be essentially studied. The most preferred method for seismic evaluation is Inelastic static
analysis or Pushover analysis due to its simplicity. Inelastic static analysis procedures include
Capacity Spectrum Method, Displacement Coefficient Method and the Secant Method. In this
study we are assessing seismic performance of G+4 regular RCC structure. The structure has
been evaluated using Pushover Analysis.
