SHM systems applied to the built heritage inventory at the territorial scale. A preliminary study based on CARTIS approach

Past seismic events have shown that the existing built heritage is strongly vulnerable to dynamic stresses induced by earthquakes. This issue concerns not only reinforced-concrete buildings but also masonry ones, which are concentrated in the historical centers that characterize the Italian peninsula. The inadequacy of existing structures to withstand the seismic actions is due to significant constructive variables, such as the materials used and the construction details, neglected in building practices. This work deals with the analysis of the built heritage through the inventory with the CARTIS (Caratterizzazione TIpologica Strutturale) form developed by the ReLUIS (Rete Laboratori Universitari Ingegneria Sismica) together with the DPC (Dipartimento Protezione Civile). Through the knowledge of the building framework, it is possible to apply Structural Health Monitoring (SHM) systems on the Town Compartments (TC) which present the highest vulnerabilities. Starting from the building inventory by detecting the TC through the CARTIS-based data, a priority criticalities scale can be drawn. The next stage consists of the implementation of proper SHM in order to provide import information about the structural integrity of buildings. The proposed methodology is illustrated in this paper referring to the suggested SHM system.
