== Abstract ==

This work presents the results of quasi-static non-linear analyses of two
masonry buildings using, for the discretization of walls, a macro-element that combines the
bending and the in-plane shear responses. The macro-element uses the force-based beam-
column element equipped with cross sections discretized in fibers, where the behavior of each
fiber is described by uniaxial constitutive models. To describe the shear response of the
structural element, the macro-element embeds a shear hinge at mid-span, with a
phenomenological non-linear constitutive model calibrated on experimental data. The
analyzed buildings are two tangibles examples of un-reinforced and reinforced masonry of
the Italian Heritage. The un-reinforced masonry building is a strategic building monitored
by the O.S.S., partially damaged by the seismic events in Center Italy in 2016. The
reinforced masonry building, a three-storey residential structure, is subject of evaluations
carried out in the ReLuis RINTC project, designed as per D.M. 2018.
