Determination of the material properties of the reinforcement for textile-reinforced concrete elements

For the design of textile-reinforced-concrete elements, it is necessary to know the material properties. The previous tests were complex and were performed not consistently. For that reason, a standardized tension-fiber-strand-test was developed. It allows to determine all material properties, which are necessary for the design. For this test, a 160 mm long fiber strand is required, which has to be cut out of a textile grid. The results show that the textile reinforcement has a linear-elastic behavior and the ultimate tensile strength approximately follows a normal probability density function. The knowledge of these tests is used to calculate the design tension strength, strain, the failure probability of the textile reinforcement, and the safety factor.
