Résumé

The possible cause at the origin of the meridional cracks in the dome of the Pantheon in Rome is addressed and investigated through a detailed three-dimensional model. Material nonlinearities, as well as a plausible sequence of the construction stages, are modeled. The parametric study set for considering the uncertainties regarding the volumetric straining and the thermal expansion coefficient of Roman concrete demonstrates that shrinkage and gravity could have been the main mechanical causes of the cracks in the early phases of the building's life. The numerical simulations show crack patterns which are in good agreement with the existing one, for both the spatial distribution and extent.
