The seismic performance of masonry churches is mainly governed by the out-of-plane mechanisms.

Abstract
The seismic performance of masonry churches is mainly governed by the out-of-plane mechanisms. Among them, the greater seismic vulnerability can be associated to the out-of-plane mechanism of the façade. If the masonry quality ensures a monolithic out-of-plane behaviour, the dynamic analysis of a rigid rocking block allows a reliable estimation of the seismic capacity of the façade, provided that the element boundary conditions are well assessed. In the present paper, the literature rocking models are adopted for a vulnerability assessment of churches' masonry façades characterized by different geometries. At this aim, fragility curves are defined by means of the Cloud Analysis approach considering earthquakes recorded in the Central Italy area to account for the record-to-record variability.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
