Numerical Simulations of Masonry Elements Strengthened through Fibre-Reinforced Mortar: Detailed Level Modelling Using the OOFEM Code

A detailed level numerical model for Fibre Reinforced Mortar (FRM) using the free, opensource code OOFEM has been recently calibrated and validated by authors through comparisonwith experimental characterization tests (i.e. pull-off tests, tensile shear bond tests). In thispaper, developed is adopted to perform simulations on FRM strengthenedmasonry elements. particular, out-of-plane in-plane bending diagonalcompressiontests are simulated adopting same modelling hypostasis characteristics andthe results compared with available in literature. Both masonry themortar modeled solid elements, yarns of fibre-based mesh truss elements interactions among components (yarns, mortar, masonry) means interface elements.Non-linear static analyses performed, considering materials interfaces non-linearity. Thesimulations result capable realistically reproduce typical performances interms global damage pattern permit investigate resistingmechanisms between components.
