Characterization of Textile-Reinforced Mortar: State of the Art and Detail-Level Modeling with a Free Open-Source Finite-Element Code

The research addressed in the paper is aimed at calibrating a numerical model developed by using free open-source finite-element code for assessment of structural performances historical masonry buildings strengthened textile-reinforced mortar (TRM) technique. TRM near-surface-mounted system, which couples inorganic matrices with fiber-based textile or meshes. main purpose to develop multiple-level approach, starting detailed modeling components and interfaces, followed computationally efficient intermediate level model, layered elements, calibration lumped plasticity-based suitable global analysis structures. In this paper, first results are presented. particular, broad literature review concerning mechanical characterization systems collected. Then, validation through comparison experimental tests available (tensile, shear bond, in-plane tests) sensitivity reported. Nonlinear static analyses were performed, considering nonlinearity composite material interfaces. was capable accounting parameters affecting behavior material, such as reinforcement ratio orientation, characteristics wire–mortar interaction proved be valid tool investigate optimization applicative details.
