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

    Author : Jonas Magnusson; Chalmers University of Technology; []
    Keywords : 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

  2. 2. Structural Behaviour of Concrete Railway Sleepers

    Author : Rikard Gustavson; Chalmers University of Technology; []
    Keywords : 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

  3. 3. Composite Action and Confinement Effects in Tubular Steel-Concrete Columns

    Author : Mathias Johansson; Chalmers University of Technology; []
    Keywords : connection; composite action; composite column; finite element analysis; bond; confined concrete; high-strength concrete; experiment; concrete-filled steel tube;

    Abstract : Composite columns composed of concrete-filled steel tubes (CFT) have become increasingly popular in structural applications around the world. This type of column can offer many advantages, for instance, high strength, ductility, and large energy absorption capacity, as well as increased speed of construction, positive safety aspects, and possible use of simple standardized connections.

  4. 4. Sliding stability re-assessment of concrete dams with bonded concrete-rock interfaces

    Author : Alexandra Krounis; Stefan Larsson; Fredrik Johansson; Ignacio Escuder Bueno; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; concrete dams; sliding stability; cohesion; shear strength; uncertainty; bond; Civil and Architectural Engineering; Byggvetenskap;

    Abstract : The shear strength of the concrete-rock interface is an important parameter in sliding stability analyses of concrete dams founded on rock and depends, in addition to the normal stress state, on the bonding conditions of the interface; concrete-rock interfaces can be either unbonded, partially bonded or fully bonded.In the Swedish guidelines for dam safety all dam-foundation contacts are treated as unbonded.

  5. 5. Anchorage of naturally-corroded, plain bars in Reinforced Concrete structures

    Author : Samanta Robuschi; Chalmers University of Technology; []
    Keywords : plain reinforcement bars; bond; concrete; anchorage; corrosion;

    Abstract : Reinforced Concrete (RC) is the most common construction material in existing structures. However, RC structures are susceptible to deterioration over time, with corrosion of the reinforcing steel as most common mechanism. Corrosion reduces strength and ductility provided by the reinforcement bars and affects their interaction with the concrete. READ MORE
