ABSTRACT
In the “Guidelines for evaluation and mitigation of seismic risk to cultural heritage” (called from now on Guidelines) different simplified mechanical models (LV1 level) have been identified which are useful for the most diffuse types of historic structures: buildings, villas and other structures with bearing walls and horizontal diaphragms; churches and other structures with large halls, without intermediate diaphragms; towers, bell towers, and other tall and slender structures. The adoption of these models though affected by uncertainties, has the ability of supplying a homogeneous evaluation on a territorial scale and, thus, is significant for the aim of designing future strengthening interventions.
