Can the diagnostic activity give a meaningful help in the design phase of a restoration on architectural heritage? How can the costs of the diagnostic phase be converted in larger savings and reduce the total cost of the restoration? These questions are answered in a pilot restoration yard, S. Sebastiano’s Oratory. This building has a lot of stratigraphic layers, and it suffers for sever statical problems. Preliminary, simplified stratigraphic analysis, aimed to identify the major changes in volume, then diagnostic analysis were focused on the area that had been recognized as the most sensitive and weak ones. The results of diagnostic and stratigraphic investigations were used to characterize the constitutive laws of the walls inside the FEM model in which, after an initial calibration phase, a static nonlinear (pushover) analysis was conducted. This approach made possible significant cost savings and a speed of times.

Abstract
Can the diagnostic activity give a meaningful help in the design phase of a restoration on architectural heritage? How can the costs of the diagnostic phase be converted in larger savings and reduce the total cost of the restoration? These questions are answered in a pilot restoration yard, S.

Preliminary, simplified stratigraphic analysis, aimed to identify the major changes in volume, then diagnostic analysis were focused on the area that had been recognized as the most sensitive and weak ones. The results of diagnostic and stratigraphic investigations were used to characterize the constitutive laws of the walls inside the FEM model in which, after an initial calibration phase, a static nonlinear (pushover) analysis was conducted.
