  1. 1. Plate buckling resistance : patch loading of longitudinally stiffened webs and local buckling

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

    Sammanfattning : Incremental launching of steel bridges is a demanding undertaking, on the erection site as well as on the designers desk. Not seldom, the structure itself is during the launching subjected to high concentrated forces on the lower flange when passing over the launching shoe or a intermediate support (e.g. column).

  3. 2. On inelastic local flange buckling

    Författare :Mikael Möller; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik; Steel Structures; Stålbyggnad;

    Sammanfattning : This thesis deals with inelastic local buckling of I-beam flanges made of steel. The main focus is on the theoretical description of the buckling process, and the influence of various parameters, e.g. the plastic modulus, yield plateau, yield stress etc. 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. Between square and circle : A study on the behaviour of polygonal steel profiles under compression

    Författare :Panagiotis Manoleas; Ove Lagerqvist; Efthymios Koltsakis; Leroy Gardner; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polygonal; RCPS; plate buckling; shell buckling; towers; transmission lines; wind turbines; high strength steel; Stålbyggnad; Steel Structures;

    Sammanfattning : The present study explores the structural properties of regular convex polygonal cross section (RCPS). Such profiles are commonly used to construct masts and towers, e.g.  transmission towers, light poles etc. LÄS MER

  7. 5. Wrinkling of sandwich panels for marine applications

    Författare :Linus Fagerberg; KTH; []
    Nyckelord :wrinkling; local buckling; imperfection; stability; anisotropy; sandwich;

    Sammanfattning : The recent development in the marine industry with largerships built in sandwich construction and also the use of moreadvanced materials has enforced improvements of design criteriaregarding wrinkling. The commonly used Hoff’s formula isnot suited for the highly anisotropic fibre reinforced sandwichface sheets of today. LÄS MER
