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. © 2022 The Authors.

Introduction In Italy, 25% of the building stock dates to years prior to 1946 and almost 54% prior to 1970 (source ISTAT, 2011), so before the enactment of modern seismic Codes. The awareness of the vulnerability of strategic structures such as hospitals is of primary importance to decide how to best allocate funds for restorations. 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 eismic pe formance of these facilitie , to decide how to best llocate funds for re tor tions. From this point f view, the fragili y curves of a building r present a powerful ol that all s to a sess the probability of exceedi g a da age threshold (or a limit state). Such information is u ful for the assessment of the structure, and for nvestigating the possibility o maintain functions during and immedi ely after arthquakes.

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.
