The awareness of the vulnerability of strategic structures such as hospitals is of primary importance as local governments have the necessity of a global overview of the seismic performance of these facilities, to decide how to best allocate funds for restorations. From this point of view, the fragility curves of a building represent a powerful tool that allows to assess the probability of exceeding a damage threshold (or a limit state). Such information is useful for the assessment of the structure, and for investigating the possibility to maintain functions during and immediately after earthquakes. In this paper the case study of an hospital facility is presented. The structure was analysed and verified by means of non-linear static analyses (Pushover) and incremental non-linear dynamic analyses (IDA). Furthermore, the fragility curves for four different damage levels (null, slight, moderate and severe) and two different seismic intensity measures were obtained.

Abstract
The awareness of the vulnerability of strategic structures such as hospitals is of primary importance as local governments have the necessity of a global overview of the seismic performance of these facilities, to decide how to best allocate funds for restorations. From this point of view, the fragility curves of a building represent a powerful tool that allows to assess the probability of exceeding a damage threshold (or a limit state). Such information is useful for the assessment of the structure, and for investigating the possibility to maintain functions during and immediately after earthquakes. In this paper the case study of an hospital facility is presented. The structure was analysed and verified by means of non-linear static analyses (Pushover) and incremental non-linear dynamic analyses (IDA). Furthermore, the fragility curves for four different damage levels (null, slight, moderate and severe) and two different seismic intensity measures were obtained.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
