Original Abstract

This paper describes two models used in the modeling strategy for textile reinforced concrete. The modeling of multi-filament yarns and of the bond between yarn and matrix is focusedon micromechanical aspects of the material behaviour. The calibration procedure of the model is explained on an example of a detailed experimental and numerical study of pull-out specimen. We demostrate the use of the model for numerical homogenization to derive effective parameters at the meso level. in parametric studies we analyze the influence of local imperfections in the microstructure arising in the production process on the meso-a nd macromechanical properties of the material.
