Summary

:

Terrestrial photogrammetry is used for geometry reconstruction of a real masonry arch, which contributes to the accurate geometric representation of a structure. While the metric model is used for implementation structural assessment tasks. Continuums as well as discontinuous (discrete) models are used and finite element analysis with commercial packages or limit analysis schemes are adopted. The resulting combination of techniques allows to evaluate the structural health of an existing complex masonry structure by taking into account geometric data of high precision, mechanical models of adequate complexity and elements of inverse analysis. Further information, like material data from the interior of the structure, is taken into account.
