English abstract:
By combining the high performance materials ultra-high performance concrete and carbon reinforcement, the construction of efficient, durable thin-walled structural elements is possible. A test series on thin-webbed textile reinforced T-beams was planned and carried out at the Institute of Structural Engineering at TU Wien in order to investigate the shear behaviour of such elements. In the experiments the efficiency of carbon textile reinforcement grids with different impregnation materials used as shear reinforcement was analysed. Furthermore, the influence of the shear span to effective depth ratio as well as the effect of prestressing on the shear carrying capacity was investigated. This article describes the experimental program and shows test results. The test series indicated that the shear performance of beams with sand coated, ASA impregnated textile fabrics is much better than for grids with an epoxy resin impregnation. Pre-tensioning of the CFRP rods is another efficient way to increase the shear carrying capacity of thin-walled carbon textile reinforced structures.
