Abstract:
Textile-reinforced concrete (TRC) is a composite material taking advantage of non-corrosive nature of fiber materials such as alkali-resistant glass (AR-glass), carbon, or aramid for designing slender and filigree structural elements. Compared to short cut fibers, textile reinforcement provides a higher degree of effectiveness because the fiber bundles are arranged in the direction of the main tensile stresses. These properties make TRC a promising construction material suitable for a wide range of structural or cladding applications. The material can be produced in plate or panel form, or as a lattice structure, each of these forms requiring different production and connection techniques. This investigation aims at identifying appropriate applications for TRC. These include façade, housing, and load-bearing systems made using slender TRC elements. Geometric and structural modifications are necessary to improve the performance of thin-walled building components made of textile-reinforced concrete. Using selected applications, this paper outlines the main principles of component design in relation to type of load, method of production, and connection details.
