Description
Summary:The paper addresses the topic of the numerical analysis up to collapse of masonry vaults. At this aim, an advanced numerical model is utilized, which requires the discretization of the structure by means of three dimensional six-noded wedge finite elements rigid and infinitely resistant and interfaces exhibiting a non linear behavior with softening. The incremental problem is solved by means of a robust quadratic programming procedure and interfaces mechanical properties are estimated by means of a consolidated homogenization strategy. Failure mechanisms and collapse loads are evaluated numerically for a case study in Italy (a masonry cross vault subjected to increasing vertical live loads up to collapse), varying mechanical properties of the vault and considering the stabilizing role played by the backfill. In light of the results obtained, limitations and possibilities of the widely diffusedtraditional approaches based on the subdivision of the vault into a series of arches are addressed.
