  2. 1. Fatigue of steel bridges : New structural details and the implementation of high strength steel

    Author : Oskar Skoglund; John Leander; Raid Karoumi; Alain Nussbaumer; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; high strength steel; fatigue; steel bridges; steel and concrete composite bridges; new structural details; linear elastic fracture mechanics; effective notch stress method; nominal stress method; Structural Engineering and Bridges; Bro- och stålbyggnad;

    Abstract : The use of high strength steel has the potential to reduce the amount of steel used in bridge structures and thereby facilitate a more sustainable construction. The amount of steel and what steel grade that can be used in bridge structures and other cyclic loaded structures are often limited by a material degradation process called fatigue. READ MORE

  4. 2. High strength steel : local buckling and residual stresses

    Author : Mattias Clarin; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad;

    Abstract : High strength steel provide designers with the possibility of creating more slender and weight efficient structures than would be possible if using steels with lower strength. To be able to do this, a structural designer needs updated and validated codes as aid in their work. READ MORE

  7. 5. A Study on Particle Motion and Deposition Rate : Application in Steel Flows

    Author : Peiyuan Ni; Pär Jönsson; Lage Jonsson; Mikael Ersson; Stein Tore Johansson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; steel flow; ladle teeming; continuous casting; non-metallic inclusion behavior; particle deposition; nozzle clogging; numerical simulation.;

    Abstract : Non-metallic inclusions in molten steel have received worldwide attention due to their serious influence on both the steel product quality and the steel production process. These inclusions may come from the de-oxidation process, the re-oxidation by air and/or slag due to an entrainment during steel transfer, and so on. READ MORE
