Original Abstract
The paper shows the correspondence between the short-range size effect occuring in a crack bridge and the long-range size effect observed on a textile reinforced concrete (TRC) tensile specimens. First an approach to modeling crack bridge behavior is introduced exploiting the evaluation of the mean performance of a multifilament bundle. The influence of imperfections in the material structure is discused using several parametric studies. The disorder in the filament bundle and the heterogeneity in the interface layer are described in form of statistical distributions. The crack bridge model provides the basis for studying the effect of the multiple cracking. In this analysis we exploit the fact that the specimen acts as a chain of crack bridges in the failure state so that it follows the weakest-link statistics. As a consequence, direct link between the local scatter in the material structure and the global size effect on ultimate strength can be easilly established.
