  1. 1. Harmonised traffic load model between Eurocode 1 - part 2 (EN 1991-2) and TRV specifications : A pilot study on reinforced concrete portal frame bridges

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :Mubashar Amir Ablahad; Nuredin Rasslan; [2023]
    Nyckelord :;

    Sammanfattning : The advancement of society has led to an increase in demand for infrastructure, particularly bridges, which are designed in accordance with different design codes. In Sweden, bridge design adheres to the Eurocode and national code (TRV specifications), with the most adverse scenario of the two codes determining the basis for bridge design. LÄS MER

  3. 2. Dynamic Analysis of Portal Frame Bridges for High-Speed Trains : A Parametric Study

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :Antonio Dib; Ramayana Salgado; [2023]
    Nyckelord :;

    Sammanfattning : A high-speed railway network is important for Sweden’s development. However, anincreasing train speed brings new challenges in bridge design due to higher bridgeaccelerations. LÄS MER

  4. 3. Soil-Structure Interaction Analysis of Portal Frame Railway Bridges : Numerical Analysis of Two Case Study Bridges

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :Nils Sandqvist; Marko Milicevic; [2020]
    Nyckelord :Soil-structure Interaction; Portal Frame Bridge; Dynamic Analysis; Perfectly Matched Layer; Train Passage Analysis; Railway Bridge; High Speed Train v;

    Sammanfattning : This thesis concerns dynamic Soil-Structure Interaction (SSI) analysis of portal framerailway bridges. Dynamic problems are common for bridges used for high speedrailway traffic. The passing trains induce harmonic loads on the bridges causingvibration amplitudes that may cause damage to the bridge structures and userdiscomfort. LÄS MER

  5. 4. Dynamic Analysis of Portal Frame Railway Bridges - Case Studies Investigating the Structural Response

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Avdelningen för Konstruktionsteknik; Lunds universitet/Institutionen för bygg- och miljöteknologi

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

    Sammanfattning : 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. LÄS MER

  7. 5. Dynamic Design of Bridges on High-Speed Railway Lines

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för byggvetenskaper; Lunds universitet/Byggnadsmekanik

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

    Sammanfattning : 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. LÄS MER
