The NOSA-ITACA code for the safety assessment of ancient constructions: A case study in Livorno

The NOSA-ITACA code has been used to study the “Voltone”, a large vaulted masonry structure located beneath the “Piazza della Repubblica” square in Livorno. The structure has been analysed in the presence of permanent and accidental loads, calculated on the basis of current Italian regulations. This case study has provided the opportunity to validate the NOSA-ITACA code and highlighted the key role played by numerical tools in assessing the safety of ancient masonry constructions.
