Masonry structures represent an important part of the cultural and architectural heritage
in Europe. The majority
of these structures is characterized by the presence
of arches that have both bearing and aesthetic
functions. They are aging and suffer the increase
of applied static and dynamic loads. Their preservation, therefore, requires the establishment of effective
intervention methods for the
maintenance and the
eventual reinforcement.

The proposed
joint thesis project aims to study the static
and dynamic behavior of brick arches designed
and tested up to failure in the laboratory under several types of loading. For the analysis
and the interpretation of obtained
results, an experimental campaign on the mechanical properties of masonry is envisaged. Compressive tests on masonry specimens will be carried out in order to characterize the stress-strain relationship as well as the compression failure mode. Direct tensile tests on the brick alone will be performed to determine
the tensile strength
and the post-peak softening
behavior. In addition,
3-point bending tests are envisaged to obtain the tensile behavior
of the brick-mortar interface. From these tests,
the necessary parameters for the material behavior
constitutive laws are determined. An experimental program will be also conducted on reduced
arcs models with the same geometric characteristics
and made with the same materials.

For the analysis at the structural scale, several approaches will be adopted
under both static and dynamic loading
conditions. The objective is to achieve
analysis tool using analytical

models and finite element method to simulate the behavior
of curved structures. The proposed tools would allow to simulate the mechanical behavior as well as the failure modes of reduced structures models. The knowledge
of the masonry behavior constitutive laws would allow to determine stresses and strains states inducing the failure of critical
sections and to perform a reliability analysis of the influence of elementary material
behavior laws on the overall
