    Author : Rikard Gustavson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; concrete; finite element analysis; three-wire strand; sleeper; bond; strand; pull-through tests; steel encased; push-in tests; bond mechanism; numerical bond model; dynamic loads;

    Abstract : The railway concrete sleeper is an important part of the railway track structure. The sleeper member requires substantial engineering skills during the design and manufacturing process in order to fulfil the requirements set by modern train traffic. READ MORE

  4. 2. Three-Dimensional Modelling of Bond in Reinforced Concrete Theoretical Model, Experiments and Applications

    Author : Karin Lundgren; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; three-dimensional analysis; splitting effects; bond; finite element analysis; reinforced concrete; pull-out tests; non-linear fracture mechanics; frame corners; splicing of reinforcement; cyclic loading;

    Abstract : The bond mechanism between deformed bars and concrete is known to be influenced by multiple parameters, such as the strength of the surrounding structure, the occurrence of splitting cracks in the concrete and the yielding of the reinforcement. However, when reinforced concrete structures are analysed using the finite element method, it is quite common to assume that the bond stress depends solely on the slip. READ MORE
