● LDPM accounts for the masonry heterogeneity and, for this reason, the cracked surfaces are never strictly symmetric respect to the vertical axis and do not appear simultaneously ● The features of non simultaneity and asymmetry of the cracks increases as the distance between the crown of the vault and the imposts increases, i.e. going from depressed vaults to groin vaults ● The evolution of the fracturing process occurs more progressively and exhibits less pronounced asymmetry in the case of depressed vaults as compared to groin vaults for which, in turn, the damage appears to be more brittle and characterized by asymmetry in the cracks distribution Acknowledgments This research was partially supported by the computational resources provided for the Quest high performance computing facility at Northwestern University which is jointly supported by the Office of the Provost, the Office for Research, and Northwestern University Information Technology References Lagomarsino, S.
