Tragwerke aus Carbonbeton sind insbesondere dann wirtschaftlich, wenn die Carbonbewehrung zum Vorspannen des Betons genutzt werden kann. Die Erfolgsgeschichte des Spannbetons basiert auf der Verwendung hochfesten Spannstahls, der es ermöglicht, dauerhaft hohe Vorspannkräfte in den Beton einzuleiten. Der Übergang vom Spannstahl zum festeren, leichte...
Für Bauwerke wird in der Regel eine Lebensdauer von mehreren Jahrzehnten angestrebt. Entsprechend dauerhaft leistungsfähig müssen die verwendeten Materialien sein. Kapitel 9 beginnt mit einer kurzen Einführung in die Grundlagen des Ermüdungsverhaltens von Werkstoffen. Anschließend werden das Dauerstand‐ und das Ermüdungsverhalten von Carbon und Bet...
In Kapitel 7 werden die Nachweiskonzepte im Grenzzustand der Tragfähigkeit (GZT) behandelt. Ausgehend von den Prinzipien des Sicherheitskonzepts werden zunächst die Herleitung von Bemessungswerten des Bauteilwiderstandes und von Teilsicherheitsbeiwerten für Bauteile aus Carbonbeton erläutert. Danach wird auf die Ermittlung der Robustheitsbewehrung...
Carbon reinforced concrete (CRC) is a material composed of a high-performance concrete and a carbon reinforcement (textile grids, lamellas, rods). Composite materials with reinforcements of other fiber materials are called textile reinforced concrete (TRC). The investigations of CRC started more than 20 years ago and the continuous development as w...
During the last years, the number of bridges built out of or strengthened by carbon reinforced concrete increased. Therefore, its behavior under fatigue tensile loading gained in importance. However, corre-sponding systematical investigations are missing. In this paper, fatigue investigations on two different mate-rial combinations with epoxy resp....
Das Prinzip der Vorspannung wird im Stahlbetonbau häufig eingesetzt, um schlanke Tragkonstruktionen oder große Spannweiten zu ermöglichen. Im Rahmen eines Forschungsvorhabens wurde das Prinzip der Vorspannung auf den konstruktiven Holzbau angewendet und deren Einfluss auf Tragfähigkeit, baudynamisches Verhalten und Bauteilverformungen untersucht. D...
Im Hoch‐ und Industriebau werden immer häufiger Stahl‐Beton‐Verbunddeckensysteme mit hohem Installationsgrad eingesetzt, in denen zur Reduzierung der Bauhöhe die Gebäudetechnik durch Öffnungen in den Trägerstegen geführt wird. Regelungen zur Bemessung von Verbundträgern mit Stegausschnitten sind in der europäischen Normung derzeit allerdings nicht...
Despite intensive research on material properties of non-metallic technical textiles for internal reinforcement in concrete, the long-term durability is not yet fully understood. In this work, results of preloaded long-term durability tensile tests on carbon-reinforced concrete specimens under environmental factors of stress, temperature, moisture...
This paper presents aspects regarding the long-term durability of textile reinforced concrete (TRC). Textile reinforcements are not influenced by corrosion as steel. However, a loss of strength caused by stress, temperature, moisture and the pH-value is recognized and can consequently cause a premature reinforcement rupture. Therefore, knowledge ab...
Textile reinforced concrete (TRC) is a high-performance composite material made of impregnated filaments and a concrete matrix with a longer service life compared to steel reinforced concrete. Due to the noncorrosive reinforcement it is possible to reduce the concrete cover and realize slender and architectural attractive concrete structures. In ad...
Anchorage behavior of textile reinforcement in thin concrete components. The safe and reasonable anchorage of textile reinforcement in concrete is relevant for both researchers and users of the innovative composite material carbon reinforced concrete. In research, major questions of bond and anchorage remain unsolved. To date, there is no design mo...
Beside the design for short-term loads, sufficient knowledge of the long-term durability is necessary to guarantee the load bearing capacity within a life cycle of a structural component. In particular this applies for textile reinforced concrete (TRC), which should show a much longer life cycle in comparison to standard reinforced concrete. The lo...

The Institute of Structural Concrete of RWTH Aachen University examines the long-term durability behavior of one material combination for new buildings as well as one material combination each for new buildings and strengthening within the scope of this project.
A test setup was developed to investigate the long-term tensile durability. The test specimens are exposed to a constant static load, temperature and water for a few months. A trend line as a function of varying load levels and time to determine the loss of strength shall be derived. This relationship serves as an approach to determine the long-term durability tensile strength. Following the long-term durability tests, the testing and verification model, which was developed at the Institute of Structural Concrete and enables the characterization of the long-term durability of carbon reinforced concrete, will be validated. The testing and verification model was derived on the basis of guidelines and standards for FRP-reinforcements.
Furthermore, the results of small-scale tensile fatigue tests flow into another testing and verification model to examine the fatigue behavior, which will also be verified in large-scale tests.
Additionally, experimental investigations of the long-term durability and fatigue bond carrying capacity are performed in this project. On basis of the test results, a testing and verification model will be developed to enable the design of the bond characteristics at the end of the lifetime.
Based on the developed testing and verification model it should be possible to determine the long-term durability and fatigue behavior of carbon reinforced concrete and consequently the long-term characteristics at the end of the service life of carbon reinforced concrete building components. The model should be applicable for a service life of 100 years. As a result of the gained knowledge on the long-term durability and fatigue behavior, the design of carbon reinforced concrete building components will be improved.
