Assessment of Seismic Vulnerability of a Reinforced Concrete Building Located in India

Assessment of Seismic Vulnerability of a Reinforced Concrete Building Located in India

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.
