There are many examples of vernacular and traditional constructions located in earthquake-prone areas that are known to have been built featuring earthquake resistant characteristics. Currently, such traditional building techniques are considered outdated by decision makers, experts and, especially, by the population. These constructions are often strengthened using modern materials and techniques. However, recent earthquakes (e.g. Umbria-Marche 1997, L'Aquila 2009) have shown that such strengthening approaches were, in fact, responsible for increasing the seismic vulnerability of such constructions.
In order to address this issue and reduce this vulnerability, the global objective of the project is:
To define a scientific framework to identify and validate the existing earthquake resistant characteristics of vernacular and traditional constructions
To define guidelines for transferring to population criteria for the adequate maintenance of those constructions and techniques in order to ensure their adequate seismic behaviour
Elaboration of an atlas of traditional seismic proof techniques in Italy, Greece and Portugal
Development of a tutorial for adequate maintenance and appropriate retrofitting of historical built up areas
Development of a report on seismic resistance of Portuguese vernacular architecture
Cross-correlation analysis with short-term hazards and long return period hazards (i.e. seismological activity)
Development of a draft Atlas of the traditional seismic proof techniques in Morocco
