Seismic vulnerability study and design of structural intervention to reduce the seismic hazard of a historical building
The Pavaglione of Lugo is a large historical building, with an approximately rectangular shape, which surrounds the Piazza Martiri. The building has a masonry bearing structure, except for the East side along Largo della Repubblica whose structure is made of concrete.
The size of the building is as follows:
As a consequence of the structural verifications of the building, for both the historical masonry part and for the East side made of concrete, tha main vulterabilities were identified and a number of remediation measures were defined.
The first intervention for the reduction of the seismic hazard were meant for the logge del quadriportico and consisted in the consolidation of the vaults above the arcades by inserting steel tie-rods on the 4 sides. Other interventions included:
Finally, during the restoration of the logge and the facades, while removing the existing plaster, some cracks of considerable size were found which required a specific study and localized consolidations of the masonry.
