Abstract

Improving the seismic response of existing buildings requires the experimental assessment of technical characteristics and residual performances toward the reliable modelling of the structural behaviour and the selection of suitable retrofitting measures. For the purpose, the normative framework and the best practice acknowledge experimental measurements from onsite and laboratory testing as paramount for diagnosis and intervention. Particularly, in the case of building stocks, with territorial assets featured by common typological and constructional layout, technicians and managers might greatly benefit by the development of digital methods and tools for data collection and sharing for two complementary goals. On the one hand, the systematic cataloguing of the buildings and their diagnostic records, eventually fragmentary as coming from different professionals either/or acquisition periods. On the other hand, the correlation and validation of the testing results from a single site against the statistical distribution over a wider case system. With reference to the above-mentioned issues, the paper is going to propose an integrated approach, based on geographic informative solutions (GIS) and photorealistic virtual tours (VR), for the structured assessment of a consistent set of buildings, by presenting the application on complementary and accessory works – guard houses, guard offices and central stations – of hydroelectric plants and dams in Central Italy. Based on the description of the proposed digital platform for remote direct access to the sites and consultation of relevant documents, reports and drawings at territorial scale, as a support for seismic vulnerability analyses, some insights on advantages and future perspectives of the proposed solutions for overall diagnosis, intervention and management of building stocks are highlighted.
