Bending Bearing Behavior of impregnated textile reinforcement for concrete elements

摘要

The current trend in the building industry shows a growing need for high-performance material with high tension and pressure strength. An innovative building material, which satisfies the wishes of the construction designer, is textile-reinforced concrete (TRC). The combination of high pressure strength concrete and corrosion-resistant reinforcement, which furthermore has high tension strength, enables slender concrete structures. The realized applications prove the existing potential. The further development of the textile reinforcement offers new possibilities for bearing structures. One main progress was the impregnation of the textiles with styrene-butadiene rubber or epoxy-resin. This process enables extensive higher failure stresses. Additionally, the durability and the strength improve. Consequently the efficiency rises. Within the scope of this paper, the bending behavior of slabs and I-beams are presented. Furthermore, a calculation approach for bending moments is introduced.
