  1. 1. Modal analysis of pedestrian-induced torsional vibrations based on validated FE models

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :Simon Chamoun; Marwan Trabulsi; [2017]
    Nyckelord :Modal analysis; validated FE models; pedestrian-induced vibrations;

    Sammanfattning : Finite element (FE) models serve as the base of many different types of analysis as e.g. dynamic analysis. Hence, obtaining FE models that represent the actual behaviour of real structures with great accuracy is of great importance. LÄS MER

  3. 2. Modelling Pedestrian-Induced Vertical Vibrations of Footbridges

    Master-uppsats, Umeå universitet/Institutionen för fysik

    Författare :Emma Zäll; [2015]
    Nyckelord :Footbridge; Pedestrian-induced; Vertical vibrations; Pedestrian-footbridge interaction; Structural dynamics; Crowd simulations.;

    Sammanfattning : A pedestrian crowd walking on a footbridge causes the footbridge to vibrate. These vibrations become an issue of serviceability and can give rise to discomfort for the pedestrians, whereby they should, to as large extent as possible, be prevented. LÄS MER

  4. 3. Dynamic Behaviour of Footbridges Subjected to Pedestrian-Induced Vibrations Studies

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Byggnadsmekanik; Lunds universitet/Väg- och vattenbyggnad (CI)

    Författare :Fjalar Hauksson; [2005]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Over the last years, the trend in footbridge design has been towards greater spans and increased flexibility and lightness. As a consequence, stiffness and mass have decreased which has lead to smaller natural frequencies and more sensitivity to dynamic loads. LÄS MER
