Original Abstract

The presentt paper shows the corespondence between the short-range size effect occurring in crack bridge and the long-range size effect observed on a textile reinforced concrete (TRC) tensile specimens. In the analysis of the effects we exploit the fact that the specimen acts as a chain of crack bridges in its failure state. The cracks are bridged by bundles consisting of several thousands of filaments that are embedded in a cementitious matrix. We include the effect of scatter of filament properties over the bundle cross section in a crack bridge and study its influence on zhe ultimate failure of the reinforced specimen.
