Resumo: A textile reinforced mortar (TRM) compatible with rammed earth structures is proposed to mitigate their seismic vulnerability. Being TRM a composite material, defining the matrix-fibre interface relationship is fundamental to predict the performance of strengthened structures. In this framework, an existing analytical approach with a newly damage model was adapted to a specific TRM composite system that is not yet addressed in literature. Hence, an adhesion-friction law was calibrated with basis on recent experimental observations. In conclusion, the proposed algorithm reproduces adequately the elastic and nonlinear response of the matrix-fibre interface and predicts with accuracy the pull-out strength of the composite.
