Multi-Scale Numerical Approach for Predicting the Mechanical Behavior of Textile Reinforced Concrete Structures

General context:

Textile Reinforced Concrete (TRC) has gained significant prominence in various fields, especially in civil engineering, where it offers an efficient solution for reinforcing deteriorated concrete structures. Consisting of multi- or uniaxial textile reinforcements embedded within a fine-grained cementitious matrix, TRC presents itself as a compelling alternative to conventional Fiber Reinforced Polymer (FRP) composites. This material boasts excellent mechanical properties, superior fire resistance (compared to polymer-based composite materials), and contributes to sustainable development objectives. TRCs, characterized by their highly anisotropic nature and nonlinear hardening behavior, rely on complex multiscale mechanisms to determine their macroscopic performance. Extensive research has been dedicated to modeling TRCs using numerical simulations (Djamai et al., 2017; Truong et al., 2016).
