An essential part of an historical building is its structure: it has a valence of historical evidence as well, and therefore it must be protected.

Then during the consolidation actions it is very important to operate trying to not upset the original structural design, supporting it and wherever possible proposing the same techniques and materials; or using new technologies compatible and reversible, also in terms of increasing the static characteristics.
The intervention of consolidation concerns both the foundations and both the elevation structures, vertical (masonry and pillars) and horizontal ( slab floors and covers): the operations are always executed in respect of ancient material and with a scientific sensitivity updated with all the new scientific techniques and the new materials.

A particular field of work, always inherent the structural consolidation, is the seismic upgrading of historic buildings that have suffered as a result of earthquakes and natural calamity, or are in areas at risk. It consists of shoring the structures in danger of collapse; then, of consolidation with both intervention techniques, traditional (such as chaining-bounding of masonry, injections of walls with compatible mixtures, replacement of decaying items with material with the same characteristics of rigidity and durability) and innovative (as seismic insulation, dissipation of energy, passive and active monitoring and active monitoring, use of composite material fibbers).
