== Abstract ==

The safety verification of in-plane loaded masonry panels requires the
evaluation of at least three different collapse conditions connected with overturning, shear
sliding, and shear – compression failure at the panels’ toe. In reinforced panels, the resisting
models should even take into consideration the presence of localized or distributed
reinforcement.
In general, the masonry is considered a Mohr-Coulomb type material not resisting tension
and plastic in compression, while reinforcement is a brittle elastic material resisting
tensile forces only [1].
The ultimate limit state is however linked with a given subset of compressed material
inside the panel area. The compressed sections are therefore varying inside the panel as a
function of the applied load. The collapse occurs in shear or overturning when one peculiar
compressed section reduces to its minimum [2].
By equating the capacity in shear and overturning it is possible to derive an explicit
statement of the minimum length of the compressed section which will be activated by a
simultaneous failure in shear and overturning. A simple inequality is detecting the real failure
mode and this allows directly computing the failure load resultant.
The procedure is very fast and can deal even with localized or distributed reinforcement
layers such as fiber strips or mesh reinforced mortars.
Some examples of panels discussed in the literature show the effectiveness of the
proposed verification procedure.
