    Sammanfattning : At the moment of writing, an expansion of the Swedish railway network has started, by constructions of new lines for high-speed trains. The aim is to create a high-speed connection between the most populous cities in Sweden - Stockholm, Göteborg and Malmö, and the rest of Europe. LÄS MER

  3. 7. Vibration mitigation of high-speed railway bridges : Application of damping devices in theory and practice

    Författare :Sarah Tell; Raid Karoumi; Andreas Andersson; Ülker-Kaustell Mahir; José Maria Goicolea; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vibration mitigation; high-speed railway bridges; damping devices; retrofit; numerical analysis; hybrid simulation; field experiment; vibrationsdämpning; järnvägsbroar för höghastighetståg; dämpare; eftermonteringsmetod; numerisk analys; hybridsimulering; fältförsök; Structural Engineering and Bridges; Bro- och stålbyggnad;

    Sammanfattning : The dynamic response of railway bridges is an important aspect to consider, as the repetitive loading from passing trains may result in excessive vibrations of the bridge deck. Several design criteria are developed in order to assure the structural safety and passenger comfort during train crossings of a bridge. LÄS MER

  4. 8. Footbridge Dynamics : Human-Structure Interaction

    Författare :Emma Zäll; Raid Karoumi; Mahir Ülker-Kaustell; Andreas Andersson; Peter Van den Broeck; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dynamics; vibration; footbridge; pedestrian bridge; human-structure interaction; runner; running loads; simplified models; Dynamik; vibration; gångbro; människa-bro-interaktion; löpare; löparlaster; förenklade modeller; Civil and Architectural Engineering; Byggvetenskap;

    Sammanfattning : For aesthetic reasons and due to an increased demand for cost-effective and environmentally friendly civil engineering structures, there is a trend in designing light and slender structures. Consequently, many modern footbridges are susceptible to excessive vibrations caused by human-induced loads. LÄS MER
