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

    University essay from KTH/Bro- och stålbyggnad

    Author : Antonio Dib; Ramayana Salgado; [2023]
    Keywords : ;

    Abstract : 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. READ MORE

  3. 2. Assessment of Ground Vibration for Early-Stage Design

    University essay from KTH/Bro- och stålbyggnad

    Author : Fadi Rafea Jameel Jameel; Patrick Francesco Joseph; [2022]
    Keywords : ;

    Abstract : Ground borne vibrations in urban areas can be caused by human activities such as railwayand road traffic, construction works and industrial manufacturing. These vibrations can playa significant role in human comfort and the disruption of vibration sensitive equipment inbuildings. READ MORE

  4. 3. Refined model for calculating the dynamic amplification factor for road bridges

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

    Author : Jens Bergenudd; [2020]
    Keywords : Dynamics; Dynamic amplification factor; Dynamic impact factor; Platooning; Soil-structure interaction; Vehicle-bridge interaction; Technology and Engineering;

    Abstract : The objective of the thesis is to simulate and evaluate vehicle-bridge interaction (VBI) due to road surface irregularities and soil-structure interaction (SSI) with different vehicle models and suspension properties. Parameter studies will be carried out for integral and slab bridges. READ MORE

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

    University essay from KTH/Bro- och stålbyggnad

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

    Abstract : 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. READ MORE

  6. 5. 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
