Framework for adaptive multi-scale simulation of textile reinforced concrete
… work at hand has originated from the research on textile reinforced concrete (TRC) that uses high strength textiles embedded in a fine-grained cementitious matrix to compensate for its low tensile strength. Moreover, this combination of materials leads to quasi-ductile tensile behavior as required …

Effect of multifilament yarn crack bridging on uniaxial behavior of textile reinforced concrete
Textile reinforced concrete (TRC) has emerged in the last decade as a new composite material combining the textile reinforcement with cementitious matrix. Its appealing feature is the possibility to produce filigree high-performance structural elements that are not prone to corrosion as it is the …

Ingenieurmodelle zum Tragverhalten von textilbewehrtem Beton
Textile reinforced concrete is a composite building material consisting of a fine-grained concrete and a textile reinforcement predominantly made of AR-glassfibers or carbonfibers. As a result of its material characteristics the textile reinforcement combines the advantages of corrosion resistance …

Theorie und Numerik einer oberflächenorientierten Schalenformulierung
… behavior of a strengthening layer made of textile reinforced concrete to strengthen a shell structure. The main focus lies on both the geometrical and physical non-linear three-dimensional shell formulation and on its transfer into an efficient finite element. The distinctive feature of the …

Zum Tragverhalten von textilbewehrtem Beton
The use of fabrics as reinforcement in concrete structures opens up many new applications for composite members. The advantages of this new composite material are a good corrosion resistance with a thin concrete cover and a high effectiveness of the reinforcement by using textiles instead of short …

Mess- und Auswertungstechnik zur Riss- und Faserdetektion bei Betonbauteilen
Measurement methods for steel and textile reinforced concrete elements have to provide precise values (in the scale of microns) in a "rough" and strongly dispersive environment. Contactless, non-destructive (NDT), optical measurement methods allow the monitoring of test data and enable the …

Textile Strukturen zur Bewehrung zementgebundener Matrices
As a complement to shortfibre reinforced air-placed concrete, textile reinforced concrete elements present new applications in the area of thin-walled elements, due to their high strength resitance. By physical and chemical examinations fibermaterial is detected, which on principle is suitable for …

Entwicklung mechanischer Modelle zur analytischen Beschreibung der Materialeigenschaften von textilbewehrtem Feinbeton
… description of the material properties of textile reinforced concrete (TRC). For the modelling of the heterogeneous structure of TRC the concept of representative volume elements (RVE) is used. RVEs are representative for the mesoscopic structure. The overall material behaviour on the …

Structural engineering model of irregular and efficient concrete beams: Application to topology optimized shapes and integrated textile reinforcement
Concrete remains one of the most widely used construction materials due to its strength, durability, and availability. However, it is responsible for a large share of the global carbon emissions. Within the 40% of the global emissions attributed to the building sector, 5-8% alone accounts for the …

Zur Dauerhaftigkeit polymergetränkter AR-Glas Bewehrungen in Textilbeton
If concrete is used as a building material the tensile strength of the reinforcement is one of the most important material properties. Traditionally concrete is reinforced with steel rebars. Textile reinforced concrete (TRC) represents a new and innovative building material, in which the reinforced …

Mechanical and fracture mechanical properties of fine grained concrete for textile reinforced composites
The development of textile reinforced concrete (TRC), where multi-axial fabrics are used in combination with fine grained concrete, allows the design of very thin-structured concrete elements with a high strength in compression as well as tension. It is the main objective of this study to determine …
