A FE model for TRM reinforced masonry walls with interface effects

We report on experimental and numerical investigations of textile reinforced mortar (TRM) strengthening systems, an innovative solution for reinforcing historical masonry structures. The experimental campaign presented in this paper is original and concerns two commercial TRM applications to single-leaf clay masonry panels. The proposed FE modelling is based on a multiscale approach is applied to simulate the behaviour of TRM reinforced masonry panels under diagonal compression tests with the possibility of simulating bed joints sliding and TRM-reinforcement debonding. This last phenomenon is frequently reported in the experimental literature and it has been observed also in our experimental tests. The numerical model is applied to simulate study the behaviour of TRM reinforced masonry panels under diagonal compression tests.
