摘要

The design and realization of seismic improvement interventions have proceeded a logic and temporal process: first at all the damage analysis, safety compatible and reversible actions, detailed surveys and direct and historic-documental investigations concerning typologies, geometries, materials and building's damages; analysis of vulnerability and seismic improvement design of interventions, all approved by Regional Seismic Service and Superintendence of Cultural Heritage; lastly, realization of works according to the project and the law, the quality and the prescriptions of control authorities.The interventions have respected principal design's purposes, in synthesis:60% of seismic improvement to the actual laws, even if not compulsory for an heritage building;compatible materials with the originals under the mechanical, physical and chemical aspect;reversible structural interventions respectful to the artefact behaviour before the realization andfocused to not modify the spatial, material and chromatic aspect of architectural complex.The principal structural interventions are: restoration, partial rebuilding and reinforcing of groinvaults, mechanical anchors and ringing elements; restoration of load bearing wall elements andimprovement of their mechanical characteristics.
