Abstract
The seismic performance assessment of historical architectural complexes is usually a complex task due to the significant uncertainties in the characterization of material properties and structural details. The reliability of analyses is also frequently jeopardized by the need of defining appropriate structural and dynamic models. Local response of selected macro elements and global response of the structure are usually distinguished. In this paper, some remarks on the discrimination between local and global behavior of architectural complexes are proposed. The study is based on a well-established vector correlation index frequently used in the field of experimental modal analysis. Results of application of the novel approach to explanatory case studies are reported, pointing out how a rational methodology can guide towards the selection of the most appropriate analysis procedure. © 2016 Taylor & Francis Group, London.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
