Paper Abstract

A wide ranging R&D Project (ISTECH) on validation and application of the Innovative Antiseismic Techniques (IATs) for the restoration of Cultural Heritage Structures (CUHESs), especially masonry buildings, based on the Shape Memory Alloys (SMAs), has been funded by the European Commission (EC), in the framework of the Environment and Climate RTD Programme. Because Traditional Restoration Techniques (TRTs) have sometimes proved inadequate in avoiding collapses and often too invasive, the use of superelastic SMA Devices (SMADs) has been developed. Theoretical and numerical studies, as well as intensive testing of material specimens, devices, structural models and in situ campaigns, show that SMADs can substantially increase the stability of masonry CUHESs exposed to an earthquake. Different SMAD types have been investigated to fulfil different structural needs and they can be custom designed taking into account each monument's characteristics. The successful results of the research and its exploitation led to important applications in Italy: the S. Giorgio Church Bell-Tower, located at Trignano, S. Martino in Rio, Reggio Emilia, damaged by the 15th October 1996 earthquake, the transept tympana of the S. Francesco Basilica in Assisi and the S. Feliciano Cathedral façade in Foligno, both heavily damaged by the September 1997 earthquake. In addition, further studies and applications of SMAD technology are foreseen in Italy in the next future, in the framework of Italian and European research projects and proposals.
