Abstract
The paper reviews research reports relating to the dome structure, also taking into account the results of own studies. Original numerical models were developed for the Dome of the Cathedral of the Santa Maria del Fiore in Florence relating to three situations: without cracks, with cracks and an example of dome strengthening. CATIA programming was used for the analysis. Conclusions related to the causes of cracks and how stress patterns differ in the three situations modelled. The way in which the dome is supported on the drum was recreated in order to understand the behaviour of the dome. For the purposes of analysing the situation with cracks, data was used from studies completed to date. An example of strengthening was introduced (in the third situation modelled numerically) making use of compressed coils at three levels, which should be acceptable from the point of view of conservation doctrine. This paper contributes to analysis of threats relating to securing one of the world’s most important historical domes.
