A Multi‐Scale Analysis of Textile Reinforced Concrete Structures

Abstract

Textile reinforced concrete (TRC) is a composite of rovings (multi filament yarns) and fine grained concrete which is used in civil engineering to fabricate new structural elements and to strengthen existing constructions. The proposed multi–scale approach is based on a hierarchical material description on the micro, the meso and the macro scale. The paper deals with structural models of the macro scale, using the detailed information of the micro– and the mesoscopic models to simulate the behavior of typical structural members made of reinforced concrete. Due to the textile reinforcement in TRC the crack opening displacements are very small. This leads to the major influence of the post cracking behavior of concrete on the overall response of the structural member. In the case of a steel and textile reinforced concrete plate the simulated crack width of the meso model is used to capture this effect within the framework of a multi–scale analysis.
