**7. Final considerations**

Knowing and understanding the structural concept of pre-existence, the materials and construction systems that compose it, in an approach and collection of information about the object, through the performance of visual inspections, soundings and / or tests that may be deemed necessary, will contribute to the design of a conscious intervention, sustained in the domain of knowledge resulting from a careful assessment of its pathologies and its causes.

The rehabilitation of masonry walls and wooden structural elements, due to the importance of their structural function in old buildings, is the object of most of the study and, consequently, of greater concern in the elaboration of intervention proposals. Notwithstanding the techniques to be adopted are classified as not very intrusive, they allow to achieve the intended objectives, without causing changes in the original structural scheme and in the various constituent preexisting structural elements.

The increase in the strength of masonry can be achieved relatively easily through reinforcement by confinement, by adding a new material (composites, mesh, sheets or metal profiles). The wooden structure must be preserved by the reconstitution / repositioning of the element with the same material and / or material different from *Structural Consolidation of Architectural Heritage DOI: http://dx.doi.org/10.5772/intechopen.99602*

the original, or by the insertion of new structural elements, whose resistance can be mobilized in order to transfer the loads between the structure to be reinforced. and that new element.

The great challenge will be to guarantee the improvement of the building's overall behavior, as a result of the careful repair / replacement of masonry and structural wood, reestablishing its structural functions now reinforced by the intervention. We tried to develop an intelligible model, from which it is intended to expose the concept of the intervention that is defended.
