Abstract:

Seismic vulnerability analysis is a fertile area of research which needs more input from seismologists and engineers. This paper focuses on the development of fragility curves for a twelve-story reinforced concrete (RC) hospital building structure in India. Fragility curve is a statistical tool representing the probability of exceeding a given damage state to the earthquake intensity. A set of earthquake records were selected from PEER data base for the development of fragility curves. Incremental dynamic analysis is performed to analyse the structure subjected to different earthquake records with various intensities based on the scaling in terms of spectral acceleration in SAP 2000. Fragility curves are developed for the same structure with and without friction pendulum isolation system (FPS). Parametric study is also conducted by varying the radius of curvature and fragility curves have been developed for all the cases. These fragility curves are used to compare their seismic performance. The structure with FPS is found to be less vulnerable to seismic hazards as compared to the structure with fixed base.

Keywords:

Fragility Curve; Incremental Dynamic Analysis; Friction Pendulum Bearing System (FPS).
