Dal restauro alla conoscenza: ricerca storica e strumenti digitali per valutare l'efficacia degli interventi sismici del XX secolo sul patrimonio religioso di Parma.

This paper provides a critical evaluation of the effectiveness of seismic reinforcement measures for historic masonry churches in Parma. The aim is to verify the performance of mid-20th-century retrofitting techniques and evaluate the influence of previous interventions on the churches' current structural behaviour. Specifically, the research focuses on interventions implemented after the 1983 earthquake that were subsequently tested by seismic events between 1996 and 2012. An integrated approach combines historical documentation with large-scale analysis using a geographic information system (GIS) database. This tool cross-references the constructive characteristics of churches, the levels of damage observed during seismic events and the seismic reinforcements implemented. This enables the qualitative factors that shape seismic response to be identified, allowing future interventions to be prioritised. The findings confirm that combining GIS tools, archival analysis, and experimental evaluations could improve decision-making and promote more informed management of built heritage.
