Abstract:
Traditional stone masonry walls are structural elements in most historic build-
ings. To preserve them and improve their ability to withstand extreme events, such as
earthquakes, it is necessary to implement effective reinforcement solutions. This paper
presents the modeling of traditional Portuguese rubble stone masonry walls, reinforced
with external steel mesh, sprayed micro-concrete layers and transverse confinement by
steel connectors, which were developed and tested experimentally in uniaxial compression.
The modeling is carried out using micro-modeling through a 2D particle model (PM).
The process of calibrating the properties of both micro-concrete and concrete is presented,
the methodology for generating the numerical models is described and the numerical
response is compared with the experimental results. The numerical results show that
the PM can adequately reproduce the experimentally observed behavior of this type of
reinforcement solution.
