ABSTRACT

As well known, since the early years of the XX century, the arbitrary and enormous use of metals, like copper and iron elements – directly left to locals skilled workers, without any preliminary structural analysis – irreversibly damaged most of the monuments belonging to the Ancient Mediterraneum historical and archaeological heritage.

The present integrated research develops starting from an experimentation on the numerical control prototyping (CAD/CAM) of stone elements for the integration of manifold architectonic handworks: it started in 2010 and it is still in progress, seeing the collaboration between Politecnico di Bari and Pi.mar s.r.l., society leader in the numerical control prototyping sector.

The results that we expect to present in this work regard the application of the experimented methodology, implemented with the use of highly performing metallic materials in the structural restoration of stone monuments, focalizing the attention on the Titanium and its alloys.

In addition to the definition of a detailed analytical methodology, contextually to the prelyminary phase of the prototyping, a Finite Element Analysis (FEA) is previewed, to evaluate the interaction between the original architectonic element components and the new integrations. To validate the Finite Element Model (FEM) a check by means of a comparison analysis between numerical and prototype model is foreseen. For the validation of the entire procedure, the sample element is a closed reply of a Doric capital fragment, relative to the so-called Egnatia Forum realized in Lecce's stone
