Rehabilitation of an Historical Theatre in Italy

Rehabilitation interventions on historical building with peculiar end-uses, such as, for example, theatres, raise problems non easy to be solved, especially when different architectural and structural functions must be ensured. The rehabilitation of the historical theatre R. Zandonai, built during the 18th century in Rovereto Italy, is a good example of how to cope with this kind of problems and to try to solve them. The will of the Rovereto municipality to rehabilitate the theatre, in order to suit the modern scenic requirements, involved the need to heighten the fly tower of about 6 meter. The deep structural modification and the reference to different design loads, led to verify the resulting structures, according to the rules and standards currently in force in Italy, among them the new Italian seismic law (O.P.C.M. 3431). The solution proposed and illustrated hereinafter, is conceived and designed with the purpose both to satisfy the severe requirements of the new Italian seismic code, and to be a reversible structure, therefore respectful to the original historical building.
