LA MECCANICA FENOMENOLOGICA PER L’ENIGMA DI NOTO

Abstract

The analytical methods may be verified on the Chiesa Madre in Noto and the Chiesa S. Nicolò l’Arena in Catania that have exasperated structural problems. The dome of the church in Noto collapsed three times in the past; it has unchanged: geometry, unreinforced masonry, unused constitutive laws. In these churches, it would seem to have the scientific luck to document all the misunderstandings, dazzlings and hazards due to MdM. The monuments must be analyzed with soil interaction; and dynamic identification is very important. But since 80’s the Geomaterials Mechanics were available, it reproduces the experimental phenomena in the analysis. The coherency between tests, analysis and MdG allows to improve diagnosis and project. Actually computers are available for the project with all d.o.f. of a monument.
