  2. 1. Fatigue Life of Riveted Railway Bridges

    Author : Björn Åkesson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; field tests; full-scale fatigue tests; steel bridges; fatigue life; railway bridges; riveted connections;

    Abstract : This dissertation, which focuses on the fatigue life of riveted steel railway bridges, is based on: - A series of full-scale fatigue tests of nine riveted stringers taken from a railway bridge built in 1896. A review of and comparison with the different full-scale fatigue tests on riveted railway bridge members, which have been conducted in other laboratories over the years, is also given. READ MORE

  4. 2. Concrete Bridges : Improved Load Capacity

    Author : Jonny Nilimaa; Terje Kanstad; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Abstract : There are many beautiful old structures around the world, some of which were designed for completely different purposes than their current applications. For example, Swedish railway bridges were only designed to carry axle loads up to 200 kN in the beginning of the 20th century, while modern loads can be twice as high. READ MORE

  5. 3. Vibration mitigation of high-speed railway bridges : Application of damping devices in theory and practice

    Author : Sarah Tell; Raid Karoumi; Andreas Andersson; Ülker-Kaustell Mahir; José Maria Goicolea; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vibration mitigation; high-speed railway bridges; damping devices; retrofit; numerical analysis; hybrid simulation; field experiment; vibrationsdämpning; järnvägsbroar för höghastighetståg; dämpare; eftermonteringsmetod; numerisk analys; hybridsimulering; fältförsök; Structural Engineering and Bridges; Bro- och stålbyggnad;

    Abstract : The dynamic response of railway bridges is an important aspect to consider, as the repetitive loading from passing trains may result in excessive vibrations of the bridge deck. Several design criteria are developed in order to assure the structural safety and passenger comfort during train crossings of a bridge. READ MORE

  6. 4. End-Shield Bridges for High-Speed Railway : Full scale dynamic testing and numerical simulations

    Author : Hesham Elgazzar; Jean-Marc Battini; Mahir Ülker-Kaustell; Morgan Johansson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; high-speed railway; end-shield bridges; structural dynamics; soil structure interaction; full scale bridge testing; controlled forced excitation; hydraulic bridge exciter; frequency response function; Civil and Architectural Engineering; Byggvetenskap;

    Abstract : The increasing need for High-Speed Railway (HSR) to reduce the travelling time requires increasing research within this field. Bridges are main components of any railway network, including HSR networks, and the optimization of their design for this purpose would contribute to a faster and more cost effective development of the HSR network.
