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

    Författare :Oskar Skoglund; John Leander; Raid Karoumi; Alain Nussbaumer; KTH; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

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

    Författare :Mattias Clarin; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad;

    Sammanfattning : 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. LÄS MER

  5. 4. Stainless steel plasticity : material modelling and structural applications

    Författare :Anders Olsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad;

    Sammanfattning : The thesis addresses stainless steel in construction with focus on plasticity and shear resistance of welded girders respectively. In the area of plasticity it comprises an account of an experimental study with emphasis on phenomenological observations followed by theorethical modelling. LÄS MER

  7. 5. Structural steel plasticity : experimental study and theoretical modelling

    Författare :Jan Granlund; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad;

    Sammanfattning : Föreliggande avhandling behandlar konstitutiv modellering av konstruktionsstål i elastoplastiskt område. Ett koncept för tvåaxlig provning i huvudspänningsplanet har utvecklats vilket sedan har använts för att generera försöksdata för att formulera en konstitutiv modell för sambandet mellan spänningar och plastiska töjningar.
