TRC is highly heterogeneous at several levels of material structures and, therefore, it exhibits a very complex failure process. Examples of interacting effects are the strain localization due to local failure mechanisms in the yarn, bond, and matrix. As a result, except for standard features, the developed models must be able to reproduce discontinuities of the displacement fields, reflect the irregularity of the material structure, special kinematics relations, and the size effect induced either statistically or energetically. This paper reviews the modeling strategies developed and applied in research and development of TRC in the collaborative research centers in Aachen and Dresden.","PeriodicalId":433029,"journal":{"name":"SP-250: Textile-Reinforced Concrete","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124902865","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cement-based composites were developed with different fabric types using cast (hand layup) process and pultrusion (impregnated) methods. Knitted fabric made from low-modulus polypropylene (PP) fabric, woven fabric made from low-modulus polyethylene (PE), and bonded glass meshes were used. Tensile and pullout tests as well as SEM observations were used to examine the mechanical, bonding, and microstructure properties. It was observed that the processing method significantly affects the bond as well as the tensile performance of the composite. The best performance was achieved for the polypropylene pultruded composites.","PeriodicalId":433029,"journal":{"name":"SP-250: Textile-Reinforced Concrete","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133113519","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Subsequently, the results were analyzed with the size effect law (SEL) of Bazant and by means of FE analysis according to the fictitious crack model (FCM) of Hillerborg.

Since such elements participate directly in load transmission in the structural framework, satisfactory fire resistance is often desirable. Experience until now, however, has been limited with respect to the behavior of textile concrete elements subjected to fire. In this investigation, four fire tests have been performed on textile-reinforced concrete sections (I-profiles), in which one side of the sections was exposed to fire. The textiles tested were AR glass, carbon, and carbon coated with styrene butadiene. These experiments demonstrated that the load-bearing behavior of textile-reinforced structural components in fire greatly depends on the textile used, their bond to the concrete, and the behavior of the concrete under high temperatures.","PeriodicalId":433029,"journal":{"name":"SP-250: Textile-Reinforced Concrete","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122089785","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The application of directed endless fiber reinforcement (i.e. textiles), so far utilized only in some limited special areas, has a high growth potential for use as reinforcement in concrete and promises several new fields of applications. In order to fulfill the reinforcement function, particular heavy-duty filament yarns are required in concrete composites. Their utilization in a multitude of possible applications can be practical only if prefabricated textile reinforcements with desired construction and properties can be manufactured efficiently. Modern textile production processes are now available with which extensive as well as spatial thread alignments in the production process can be implemented to produce novel textile reinforcement for applications in concrete. This paper provides an overview of the relevant textile formation methods for reinforcement textiles. A review of testing methods to characterize textile properties is also provided.","PeriodicalId":433029,"journal":{"name":"SP-250: Textile-Reinforced Concrete","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132729684","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Because of different bond performance and material properties of textiles compared to reinforcing steel, the load-bearing behavior of TRC differs from that of ordinary reinforced concrete. As a consequence, the design methods for ordinary reinforced concrete cannot be directly applied to TRC structures. This paper investigates the load-bearing behavior of TRC. Design methods for TRC are derived considering different textile properties and different loading conditions such as tension, bending, and shear. Based on the extensive theoretical and experimental investigations conducted, design methods have been derived that allow the dimensioning of TRC structures. Further investigations are aimed at identifying appropriate applications for TRC. The results of theoretical and experimental investigations conducted have been put into practice by producing TRC elements for applications such as facade elements, formworks, and tanks.","PeriodicalId":433029,"journal":{"name":"SP-250: Textile-Reinforced Concrete","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128944090","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since sufficient fibers can be included when glass fiber reinforcement is introduced in the form of textiles, a distinct strain-hardening behavior can be obtained beyond the introduction of matrix multiple cracking. However, to improve the range of applications in which this material can be used, stress-strain behavior characteristics and crack control should be globally understood, as well as the parameters influencing them. Both properties are discussed as function of fiber volume fraction, matrix-fiber bundle interface, and the influence of complex fiber-matrix interaction. The constitutive material model that is used in this paper is based on the well-known ACK-theory (Aveston-Cooper-Kelly), but includes the fact that matrix cracking occurs progressively with increasing strength and not at one deterministic stress level.","PeriodicalId":433029,"journal":{"name":"SP-250: Textile-Reinforced Concrete","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116549583","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The lost formwork element was designed to carry the load of a 200 mm (7.87 inch) thick layer of fresh concrete. The influence of different reinforcement textiles was examined. The load bearing capacity and the serviceability were investigated by 4-point bending tests. The bond to the top concrete layer was examined by bending tests carried out on composite beams consisting of the formwork element with a top concrete layer. To test the load-bearing capacity when the element is used as part of a one-way spanning slab, composite slabs of three formwork elements with steel-reinforced top concrete were cast and tested. The resistance to fire of the integrated formwork elements was investigated by conducting standardized fire tests. The results from this investigation demonstrate that the developed textile reinforced concrete formwork element successfully achieved the designed load-bearing capacity and serviceability requirements.","PeriodicalId":433029,"journal":{"name":"SP-250: Textile-Reinforced Concrete","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128046858","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
