Abstract

Presented in this paper are the main features and first results of studies performed by ENEA, with the cooperation of the University of Bologna, for improving stability, in particular seismic protection, of cultural heritage. These studies are being carried out in the framework of the ISTECH project, funded by the European Commission. They concern the evaluation of the benefits related to the use of shape memory alloy devices for the seismic rehabilitation of the aforesaid structures. The use of such materials across gaps or fissures has not only a strengthening function, by making the structure capable of absorbing deformations due to creep and settlements, but also may add considerable energy dissipation if the structure deformation is sufficiently large. The great interest for cultural heritage is related to the limited encumbrance. Until now, considered have been a church damaged by the 1980 Campano-Lucano (Irpinia) earthquake and more recently, bell towers damaged by the 1996 Modena & Reggio Emilia (Novellara) earthquake.
