The effect of earthquake causes loss of life and property in many places all over the world. This
creates the need to assess the seismic performance of the structures. The latest development leads
to finding the direct losses and damage states of the buildings for various intensities of earthquake
ground motions. In the present study, seismic vulnerability assessment was done for a medium rise
building (G+5). The design peak ground acceleration of 0.16 g and 0.36 g were considered for the risk
assessment. The nonlinear static pushover analysis was done to fine the performance point, spectral
acceleration and corresponding spectral acceleration by Equivalent Linearization (EL) method given
by Federal Emergency Management Agency (FEMA-440). The four damage states such as slight,
moderate, extreme and collapse has been considered as per HAZUS-MR4. The seismic vulnerability
in terms of fragility curves was developed to evaluate the damage probabilities based on HAZUS
methodology. The discrete and cumulative damage probability was found for all the damage states of
the building which shows the building at 0.16 g experience slight damage whereas at 0.36 g the
moderate damage state equally becomes predominant.
