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.

Mechanical Behavior of Textile Reinforced Concrete (TRC) / Concrete Composite Elements

“…Significant experimental and analytical work focusing on bond mechanisms in TRC has been conducted by Krüger et al (2001), Krüger et al (2002a), Krüger et al (2002b), Banholzer (2004), Chudoba et al (2007) and Jesse et al (2008), to mention a few. A combination of the micro-and mesoscopic models leading to the so-called Micro-Meso-MacroPrediction Model (MMM-PM) has been proposed by Lepenies et al (2008). In this work, and in sake of generalization and simplification that should characterize any design tool, textile-to-matrix interaction is considered to be primarily dependent on the rovings' coating (or its absence thereof).…”

Flexural Behavior of a Novel Textile-Reinforced Polymer Concrete

“…The selection of the span-to-depth ratio is congruent with the literature [ 8 , 66 , 67 , 68 ]. The span-to-depth ratio selected is also suitable given the relatively high deformations reported for TRC specimens and since most of the TRC applications are for shell-like structures [ 1 , 2 , 6 , 7 , 24 ]. The deflection at the midspan location was measured using a linear variable differential transducer (LVDT).…”

“…Textile reinforced concrete (TRC) is a cementitious composite that has been recently introduced to civil infrastructure as new precast elements and to strengthen deteriorated structures due to its lightweight, durability, design and installation flexibility, and in- and out-of-plane structural performance [ 1 , 2 , 3 , 4 , 5 ]. Typically, TRC is created by incorporating high-performance textile reinforcement made of continuous multi-filament yarns (e.g., glass, polypropylene, polyamides) into a matrix comprised of cement as a binder and small-size, well-distributed aggregate [ 6 , 7 ].…”

“…Ingolf G. Lepenies1et al [25]proposed a multi-scale model based on a hierarchical material description on the micro, the meso and the macro scale. A new kind of a cementitious composite of textile reinforced concrete (TRC) is analyzed.…”
