Abstract
The damage to the buildings during recent earthquakes has demonstrated the need of seismic evaluation which is used to predict the probability of damage to the building. This paper describes the vulnerability assessment of reinforced concrete buildings using fragility curves.Fragility curves are used to describe the probability of damage being exceeded a particular damage state. For the development of fragility curves, guidelines given by HAZUS technical manual have been used. For the analysis, the RC buildings were modelled in SAP 2000 v14. Non-linear static analysis procedure is used for the analysis of RC buildings.The pushover analysis is carried out as per the ATC40 guidelines. Capacity curve is generated as a result of pushover analysis. Results from pushover analysis are used for plotting fragility curves. The Fragility Curves are plotted considering Spectral Displacement as a ground motion parameter. Various ‘damages states’ are used to describe the damage level of the building given in HAZUS technical manual. Finally, using constructed fragility curves the spectral displacement values that satisfy the ‘slight’,‘moderate’, ‘extensive’, ‘complete’ performance level requirements were estimated. The fragility curves developed from the analysis were used to study the seismic performance of building models.
