ABSTRACT
ABSTRACT: The existing civil and architectural facilities would take advantage from the availability of non-destructive investigation techniques, whose outcome is the evaluation of the current state of a structure. Different approaches have been pursued, either in a targeted way or integrated by analytical models able to drain the necessary information on the structural response. Usually, a comparison of current versus initial values of the main dynamic parameters of the system drives the diagnostics, which consists of detecting the presence and of identifying the entity and the location of some local deterioration or damage.
