Abstract: Textile reinforced concrete (TRC) is an innovative high performance composite material which has revealed many promising attributes in various applications but has not yet reached its recognition due to a lack of available design tools. To be able to reach this stage, standardized test methods and reliable numerical models need to be established to reduce uncertainty and the need for extensive experimental studies. The aim of this paper is to present an approach which links experimental methods to simplified numerical analyses. The applied experimental methods are categorized according to the mechanical behaviour features they encompass: material, interaction and global levels. A 2D-macro-scale FE-model was developed, as a case study, using experimental data from material and interaction levels as input. The outcome of this analysis was compared to the global level data to identify the effects of key parameters in FE-modelling of TRC. Comparison of the FE-analysis results and the experiments indicated that the developed modelling method de-scribes certain mechanisms adequately while posing certain limitations. It was shown that the bond between the textile and the concrete is a very critical input parameter which af-fects crack development, deflections, and failure mechanisms.
