Freie Formen mit Textilbeton

Abstract

Textilbeton ist ideal, um Leichtbau mit Beton zu betreiben, da bereits mit sehr dünnen Schichten eine hohe Tragfähigkeit erreicht werden kann. Aufgrund der Leichtigkeit und der Flexibilität seiner Bewehrung ist Textilbeton vor allem prädestiniert dafür, freie Formen zu realisieren. In Verbindung mit innovativen Herstellungsmethoden besteht zudem die Möglichkeit, eine neue Formensprache im Betonbau zu etablieren. Dass dieses Potenzial nicht nur Ingenieure und Architekten interessant ist, sondern auch für Künstler und Designer, wird im zweiten Teil des Beitrags gezeigt. Free forms with TRC Textile reinforced concrete is ideal to build lightweight concrete structures, because a high load capacity can already be reached with very thin layers. The textile reinforcement is lightweight and flexible. Therefore, TRC is especially predestined to realize free forms. In combination with innovative production methods, we also have the option to develop a new distinctive design idiom in concrete construction. In the paper we also show, that this enormous potential is not only interesting for engineers and architects, but also for artists and designers.

Numerical Modeling of Non-Uniformly Reinforced Carbon Concrete Lightweight Ceiling Elements

“…As previously specified in (7), the contribution of the matrix stressσ m in a mixed cross section is introduced as an average of contributions σ (j) m determined from the tensile tests characterizing the matrix behavior in combination with the applied types of fabric reinforcement j. With regard to this fact, the contribution of the matrix stress to the cross section is nearly proportional to the area of matrix within the cross section.…”

“…The combination of fine aggregate concrete matrix with textile fabric reinforcements made of carbon enabled the construction of lightweight, thin concrete shells with curved geometries [3]. Experimental investigations of structural behavior were performed for large-scale shells with strain-hardening behavior serving as roof elements [4][5][6], pedestrian bridges [7,8], sandwich panels and facade elements [9][10][11]. Because of the non-corrosive nature of the reinforcement, a high sustainability and durability of this type of structures are provided.…”

Shells Made of Textile Reinforced Concrete - Applications in Germany

“…Due to the slim dimensions of the single elements, however, there is still a very soft superstructure. This U cross-section had to be [28] considered and modeled as a shell in order to be able to estimate the load bearing capacity correctly. Whether the superstructure acts more as a bar or rather a shell depends on the concrete load case.…”

“…Textile reinforced concrete has not only a great potential in construction, but it is also an interesting material for designers and artists, e.g. Scheerer & Michler [28], due to its typical flexibility properties, that enables it to be formed in thin and light structures.…”

“…Es können somit filigrane Bauteile mit geringen Betonüberdeckungen ausgeführt werden. Das hohe Potenzial der Textilbetonweise wurde bereits in zahlreichen erfolgreich umgesetzten Forschungs‐ und Praxisprojekten aufgezeigt .…”
