  1. 1. Patch loading : resistance of steel girders subjected to concentrated forces

    Författare :Ove Lagerqvist; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad; Construction Engineering and Management; Byggproduktion;

    Sammanfattning : Different aspects concerning the resistance of steel girders subjected to concentrated forces have interested a large amount of researchers all over the world. The subject most dealt with among researchers is what is called "patch loading", a concentrated force applied at one flange. LÄS MER

  4. 3. 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

  5. 4. On failure of high strength steel bridge roller bearings

    Författare :Pourya Noury; Ove Lagerqvist; Kjell Eriksson; John Yates; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stålbyggnad; Steel Structures;

    Sammanfattning : This thesis is concerned with failure analysis of high strength steel bridge roller bearings.Paper Adescribes how the commonly used Hertz formulas for contact stresses underestimate the actual stresses in practice due to temperature differences, misalignments and other construction-related conditions.

  7. 5. Flexural Buckling of High-Strength Steel Columns

    Författare :Gabriel Sabau; Ove Lagerqvist; Torsten Höglund; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stålbyggnad; Steel Structures;

    Sammanfattning : The European standards dealing with design rules and recommendations for steel structures have been under revision in the past years due to the increased use of high-strength steels. High-strength steels popularity increased at a steady pace in the last decades since they allow for more light-weighted solutions than conventional steels. LÄS MER
