Abstract

The increasing focus on construction aspects of historical architecture, associated with the increased analysis of techniques through the archival re-searches, but even more the restorations that stud historic centres for public and private initiatives, all these actions have allowed to find wooden frameworks, where they weren’t recognizable to a discerning eye; many theatres are entirely built using a wooden structure, associating to interior halls of aristocratic pal-aces, churches, convents or monasteries and also the basic and widespread urban tissue testifies the common application of these structures, with recurring appli-cations and originalities linked to specific applications. The Sicilian traditional architecture identifies in wooden frameworks a significant part of its construc-tion lexicon: the validity of system directs the recovery to conservation, protect-ing the existing structures (lightweight partitions, load-bearing walls) and sug-gesting philological reconstructions, where they have been possible: often the wooden framework limits the collapse of the masonry on which it rests, offering an useful anti-seismic defence (structural cross bracing and chaining system), favouring the absorption of the same seismic actions and improving the connec-tion of walls. The wooden framework also has a lower weight, avoiding signifi-cant overloads on the underlying structures and, in comparison to the stiffness of masonry, it results elastic and deformable because of inevitable sliding of its elements constituting the structural nodes and technical joints. Currently it’s preferred, where the original construction system appears reliable, to maintain these wooden structures rather to purpose their demolition, and when the con-temporary survey or documentary sources attest their presence and value as earthquake-resistant structures it’s a common practise to rebuilt them, according to local construction tradition. In this study we would analyze the construction methods, wooden or iron connections and the possible permanence, in continu-ity with the past, through appropriate restoration works, maintaining the original character during the eventual reconstruction/consolidation interventions.
