  1. 1. FE-Modelling of Composite Girder tests

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Holger Berggren; Bergstedt Ola; [2024]
    Nyckelord :shear connector; post-installed; coiled spring pins; composite girder; partial composite action; finite element method;

    Sammanfattning : Many of the existing steel-concrete bridges may need to be strengthened, as heavier vehicles areallowed on the Swedish roads. These bridges could possibly be strengthened by post-installingshear connectors. The shear connectors may enhance the load-bearing capacity through a higherdegree of composite action between the steel and concrete interface. LÄS MER

  4. 3. Telescopic Tower Facilitating Installation of ≥12 MW Offshore Wind Turbines

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Martin Pettersson; [2020]
    Nyckelord :Installation of Offshore Wind Turbines; Telescopic Tower; Pin and Hole Jacking System; Friction Connection; Installation av vindkraftverk till havs; teleskopisk torn; hydraulisk jacksystem; friktionskoppling;

    Sammanfattning : The trend of offshore wind power is bigger and bigger wind turbines. Turbines are now becoming so big that existing installation vessels no longer are feasible and new bigger installation vessels are needed. LÄS MER

  5. 4. Impact loads on the self-elevating unit during jacking operation

    H-uppsats,

    Författare :Viktor Daun; Fredrik Olsson; [2019-07-03]
    Nyckelord :Farkostteknik; Vehicle Engineering;

    Sammanfattning : The renewable energy resource of offshore wind is believed to have a great potential in playing an essential role on the future energy market in Europe, but there are complications such as harsh weather and low accessibility. To manage this, most offshore wind turbines of today are installed and maintained using self-elevating units (SEUs). LÄS MER

  7. 5. Lyft av liggtimmerhus. Timmermannens erfarenheter och metoder

    Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvård
