Abstract
Historical earthquake catalogs are one of the building blocks for the assessment of seismic hazard. Despite many years of research in the archives, many earthquakes remain poorly known. New sources of informationare hence required.Among these, historical buildings are witnesses of natural catastrophes recorded in their walls as structural disorders, repairs, and restorations. Our project aims to study past earthquakes using buildings as “stone seismometers”, analyzing the seismic ground motions required to explain building repairs/disorders, or their absence. The goal is to demonstrate that archaeological characterization of post-seismic repairs on buildings can be successfully used to infer key ground motion and earthquake source characteristics of historical earthquakes.An interdisciplinary connecting “ArChaeology, inventory of RecOnstruction, Seismology and Structural engineering” (ACROSS) is introduced to gain such knowledge. Based on innovative techniques to inventory repairs in the building archaeology; seismic input signals consistent with the seismotectonic context; digital building models implementing realistic geometry and construction materials as well as robust modelling of masonry behaviour, the ACROSS method is declined in five steps, 1. Collecting the data produced by the archaeology of the buildings and the study of historical sources.2. Identification of damage mechanisms. 3. Definition of the digital building model used for seismic dynamic analysis.4. Comparison of the numerical analysis results, based on previous steps, with repairs and damage mechanisms.The method is applied to six bell towers located in the Mugello basin (Tuscany, Italy). They were affected by many historical earthquakes at least from the middle of the 16th century.
