Zum Verbundverhalten von Spannstahl mit sofortigem Verbund unter Betriebsbeanspruchung
Slender and long-spanning structural members are a characteristic of current architecture. Prestressing of concrete reduces the required depth and extends the possible span of girders and slabs. Therefore the influence of sustained and cyclic loading becomes more and more important. While many …

Zur hierarchischen und simultanen Multi-Skalen-Analyse von Textilbeton
… und der einbettenden Matrix. Für das Verbundverhalten von Rovings in einer Feinbetonmatrix wird, ausgehend von einer Rovingapproximation mit superelliptischem Querschnitt, die partielle Imprägnierung des Rovings und die daraus resultierende Verbundwirkung identifiziert und simuliert. …

Spannbetonfertigteile mit teilweiser Vorspannung aus hochfestem Beton
The behaviour of prestressed and precast members made of high strength concrete is strongly influenced by the increase in bond strength of the pretensioning tendons. In this paper the investigation results of the bond properties of prestressing steel in the transmission zone of prestress, in the …

Textile Strukturen zur Bewehrung zementgebundener Matrices
As a complement to shortfibre reinforced air-placed concrete, textile reinforced concrete elements present new applications in the area of thin-walled elements, due to their high strength resitance. By physical and chemical examinations fibermaterial is detected, which on principle is suitable for …

Bond Behaviour of a Multi-Filament Yarn Embedded in a Cementitious Matrix
Although the bond of a strand in a cementitious matrix is certainly predominated by the bond properties between filaments and matrix, more detailed information is needed to evaluate the failure mechanisms of such a complex system under a pull-out load and hence to allow an analytical and numerical …

Zum Verbund- und Querkrafttragverhalten von Spannbetonträgern aus ultra-hochfestem Beton
Within the priority program SPP 1182 of the German Research Foundation (DFG), the bond behavior of strands in ultra-high performance concrete (UHPC) as well as the shear bearing behavior of pretensioned girders were investigated at the Institute of Structural Concrete at the RWTH Aachen University. …
