This study presents the evaluation of various structural analysis approaches to theoretically determine the bending resistance of flexural reinforced concrete elements strengthened with textile-reinforced mortar (TRM), which are gaining more and more attention as external strengthening layers. To assess the increase in capacity due to strengthening, multiple experimental studies from the literature were evaluated. Different structural analysis approaches for determining the flexural strength increase were tested against the experimental data. Finally, the consideration of strain limits for the textile layers, as also applied in the dimensioning of externally bonded fiber-reinforced polymers, proved to be the most reliable analytical approach.
