   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. Dynamic Behaviour of Reinforced Concrete Structures: Analyses with a Strong Discontinuity Approach

   Author : Per-Ola Svahn; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ; reinforcement; concrete; cohesive crack; anisotropic damage; X-FEM;

   Abstract : Reinforced concrete is a widely used construction material. To obtain efficient design of new structures and to verify the real mechanical behaviour of existing ones, it is necessary to improve the understanding of advanced structural analyses of reinforced concrete structures.

5. 3. Assessment of fatigue resistance and strength in existing concrete structures

   Author : Håkan Thun; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

   Abstract : During the last few decades, it has become more and more important to assess, maintain and strengthen structures like bridges, dams and buildings. This is mainly due to the fact that: (a) many structures are getting old and many have started to deteriorate, (b) there is sometimes a need to increase the load carrying capacity of an existing structure due to e.
