The assessment of seismic risk of buildings in archaeological areas presents several distinctive features.

Abstract
The assessment of seismic risk of buildings in archaeological areas presents several distinctive features. But the most critical issue is represented by the procedure relating to survey, estimate of degradation and mechanical characterization of materials, that must allow to define a model encompassing all the building features and to compute reliable safety indices. The information about the vulnerability of archaeological heritage is customary acquired primarily through a phase of cataloguing based on the assessment and analysis of the individual components (foundations, masonry walls, floors and roofing, stairs, connections, flooring, coatings, etc.) and an estimate of the extent and seriousness of the different forms of degradation. This paper shows the procedure performed to study the ‘Villa of Mysteries’ in Pompeii, which is based also on a multidisciplinary approach to obtain a very refined structural model, that allows several types of structural analyses. The building structure is, in fact, characterized by abrupt changes of material since underwent some repairs and strengthenings over the years, some of which made using reinforced concrete elements. This affects the vulnerability of the building: and only through an in-depth analysis of masonry and a detailed structural model based on a laser scanner survey it has been possible to consider all the main features characterizing the static and seismic safety and identify the most critical points of the structure.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
