  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

    University essay from KTH/Bro- och stålbyggnad

    Author : Mubashar Amir Ablahad; Nuredin Rasslan; [2023]
    Keywords : ;

    Abstract : 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. READ MORE

    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

  4. 3. 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
