  1. 21. Dynamic Analysis of Portal Frame Railway Bridges - Case Studies Investigating the Structural Response

    University essay from Lunds universitet/Avdelningen för Konstruktionsteknik; Lunds universitet/Institutionen för bygg- och miljöteknologi

    Author : Benjamin Berg; Pontus Nyberg; [2020]
    Keywords : Dynamic Analysis; Portal Frame Bridges; High Speed Trains; Railway Bridges; Finite Element; Resonance; Modal Analysis; BRIGADE Plus; Technology and Engineering;

    Abstract : As the world continues to see an increase in carbon dioxide emissions, actions aiming towards reducing man's negative impact on the environment are paramount. To be able to compete with the air travel industry, the Swedish Transport Administration suggests a vast expansion of the existing railway system. READ MORE

  3. 22. A 3D sliding bearing finite element based on the Bouc-Wen model : Implementation in Abaqus

    University essay from KTH/Bro- och stålbyggnad

    Author : Rémi Lantoine; [2020]
    Keywords : Railway bridge; dynamics; resonance; sliding bridge bearings; finite element; Abaqus; friction; steel; Teflon; PTFE; Bouc-Wen model; friction coefficient; temperature; heating;

    Abstract : As rail transportation is significantly more virtuous than airplanes or cars in terms of greenhousegases emissions, its development is being encouraged in several European countries, includingSweden. In addition, the development of railway lines on which trains can travel at higher speeds ismade in Sweden with the integration of existing infrastructure. READ MORE

  4. 23. Dynamic Design of Bridges on High-Speed Railway Lines

    University essay from Lunds universitet/Institutionen för byggvetenskaper; Lunds universitet/Byggnadsmekanik

    Author : Felicia Nilsson; Filippa Dahl; [2019]
    Keywords : High-speed railway bridges; bridge-train resonance; structural dynamics; modal dynamics; time stepping; soil-structure interaction; finite element method; BRIGADE Plus; Technology and Engineering;

    Abstract : In recent years, high-speed railway has been on the upswing in the public debate, as Swedish authorities have affirmed the plans of a high-speed corridor connecting Stockholm, Gothenburg and Malm¨o. The track speed limit is not fully determined, but will be in the range of 250-320 km/h. READ MORE

  5. 24. Photogrammetry for health monitoring of bridges : Using point clouds for deflection measurements and as-built BIM modelling

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Joel Delehag Lundmark; [2019]
    Keywords : ;

    Abstract : Road and railway bridges play a crucial role for the infrastructure network in Sweden to work smoothly and keep the traffic flowing. Damage to a bridge can have catastrophic consequences if they are not corrected properly and in due time. READ MORE

  6. 25. The Nordic Prediction Method For Railway Traffic Noise : Improvements of the current corrections forrailway bridges, switches and crossings

    University essay from KTH/Byggnadsmaterial

    Author : KRISTÍN HELGADÓTTIR; RAGNHEIÐUR BJÖRNSDÓTTIR; [2019]
    Keywords : The Nordic Prediction Method; Railway traffic; Railway noise; Noise measurements; Acoustics; Steel bridges; Concrete bridges; Switches; Railway crossings; Correction factor; Correction for track condition;

    Abstract : Railway noise is a very important and growing health hazard in today´s society.Railway systems pass through towns and cities and create noise. When trainsride through or over railway bridges, switches and crossings the noise increasessubstantially, causing great annoyance to the residents in the area. READ MORE
