Abstract

Strong earthquake in recent history has caused major physical damage and casualties. Parts
of India facing destructive earthquakes are at high risk. Given that a majority of the population lives
in areas vulnerable to earthquake, such awful incidents are likely to occur again in the near future.
Moreover, it is not easy for a developing country such as India to cope with the major direct and
indirect economic losses following each devastating earthquake. Since in this country many
reinforced concrete buildings are not built according to the current building code, seismic activity is
not taken into account during the selection of the structural framework and in most cases inspection
during the construction process is not adequate which in turn causes deficiencies such as poor
concrete quality, insufficient reinforcement details etc. Therefore, quantifying the danger of an
earthquake and designing disaster reduction plans is essential. An extensive and interdisciplinary
study is needed to achieve this aim.
This study describes the method by which current engineering structure and building stock can be
classified as vulnerable. The method used to measure the seismic efficiency of reinforced concrete
frame structures is the fragility curve, and by definition, the fragility curve offers estimates of the
probabilities of approaching or exceeding different limit states at defined ground shaking intensity
levels for an individual structure or structural population. A limit state, which is in the same context
as the response, usually represents a condition of harm or an usage restriction. From the established
fragility curves the seismic susceptibility of these structures to different earthquake can be
interpreted.
