Zur Krafteinleitung bei externer Vorspannung
The thesis "Transmission of Prestressing Forces of External Tendons" covers the anchorage and deviation of external prestressing tendons in hollow-box-girder bridges. At first, the behaviour of different anchorage constructions was derived from the analysis of three full-scale tests. Numerical …

Zur Modellierung des Zugtragverhaltens von textilbewehrtem Beton
This thesis has been written within the scope of the project D3 "Simulation of textile reinforced elements" which is part of the collaborative reserarch centre SFB 532 "Textile Reinforeced Concrete – Basics for the development of a novel technology". It is a contribution to the multi-scale (micro, …

Zum Durchstanzen von Flachdecken unter Berücksichtigung der Momenten-Querkraft Interaktion und der Vorspannung
Due to their economic and architectural benefits, flat slabs made of reinforced or prestressed concrete are widely used for high-rise and residential buildings. In the surrounding area of slab-column connections, high moment and shear stresses arise, which can cause both bending failure and shear …

Zum Tragverhalten von textilbewehrtem Beton
The use of fabrics as reinforcement in concrete structures opens up many new applications for composite members. The advantages of this new composite material are a good corrosion resistance with a thin concrete cover and a high effectiveness of the reinforcement by using textiles instead of short …

Zum Schubrissverhalten von Stahlbeton- und Spannbetonbalken aus Normal- und Hochleistungsbeton
Most of the recent research results trace back the portion of the shear capacity exceeding the truss model of Mörsch, exclusively to aggregate interlock forces. In this way, the concrete contribution is considered solely by a more flat strut inclination q and accordingly the whole shear capacity is …

Zur Zuverlässigkeit der Bemessung gegen Durchstanzen bei Einzelfundamenten
The safety and reliability of structures is influenced by the uncertainties of actions and resistances. The random character of the structural variables can be considered via probabilistic approaches and the failure probability can be calculated as a measure for safety. The concept of limit states …

Zum Tragverhalten von Betonbauteilen mit Faserverbundkunststoff-Bewehrung
This thesis deals with experimental and theoretical investigations on the load carrying behaviour of concrete members with Fibre Reinforced Polymers (FRP). Besides a detailed description of the FRP bars, which are used as non-prestressed reinforcement in concrete structures, this thesis contains …

Zur Verbundverankerung bei Vorspannung mit sofortigem Verbund in Hochleistungsbetonen
Prestressed concrete structures with pretensioned strands have been accomplished for several years. Generally, normal strength concrete with a density of 2.4 kg/dm³ and a cylinder compressive strength up to 50 N/mm² is used. In prestressed concrete, the bond anchorage behavior of prestressing …

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 …

Ingenieurmodelle zum Tragverhalten von textilbewehrtem Beton
Textile reinforced concrete is a composite building material consisting of a fine-grained concrete and a textile reinforcement predominantly made of AR-glassfibers or carbonfibers. As a result of its material characteristics the textile reinforcement combines the advantages of corrosion resistance …

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. …
