  2. 1. A theory of bond applied to overlapped tensile reinforcement splices for deformed bars

    Author : Ralejs Tepfers; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Concrete; splitting failures; confinement; deformed bars; tensile overlap splices; bond theory; fatigue; concrete cover splitting; reinforcement;

    Abstract : A bond theory for deformed reinforcing bars in concrete is elaborated taking into account different stages in development of final rupture occurring as splitting or pull-out. The concrete cover splitting resistance is modelled for a thick-walled concrete ring in elastic and plastic stages. Different final possible failure modes are analysed. READ MORE

  4. 2. Application of Fracture Mechanics to Concrete Bridges. Finite element analyses and experiments

    Author : Mario Plos; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reinforced concrete; reinforcement splice; full-scale test; shear failure; fracture mechanics; fatigue test; static test; concrete frame corner; non-linear finite element analysis; concrete bridge;

    Abstract : Material models based on fracture mechanics together with non-linear finite element analyses have been used in combination with experiments to study the behaviour of reinforced concrete bridges. The work covers two aspects of interest in the design of concrete bridges.* The shear behaviour was studied in full-scale tests on two highway bridges. READ MORE

  5. 3. 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

  6. 4. Bond and Anchorage of Ribbed Bars in High-Strength Concrete

    Author : Jonas Magnusson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; non-linear finite element analysis; high-strength concrete; anchorage; ribbed bars; beam tests; bond; confinement; normal strength concrete; pull-out tests;

    Abstract : For structural utilisation of high-strength concrete, a good understanding of the bond and anchorage behaviours of ribbed bars in this specific material is essential. The research project aims to increase the knowledge of bond and anchorage behaviours of ribbed bars in high-strength concrete. READ MORE
