  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

  5. 3. LCC Applications for Bridges and Integration with BMS

    Author : Mohammed Safi; Håkan Sundquist; Raid Karoumi; Milan Veljkovic; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bridge; Management; life-Cycle Costing; LCC; Bridge Management System; SRA - Transport; SRA - Transport; Järnvägsgruppen - Infrastruktur; Järnvägsgruppen - Infrastruktur;

    Abstract : Bridges are vital links in many transport networks and represent a big capital investment for both governments and taxpayers. They have to be managed in a way that ensures society's needs are optimally met. In many countries, bridges are mainly managed using bridge management systems (BMSs). READ MORE

  6. 4. Fatigue of existing steel bridges : Reliability and risk analyses for decision-making

    Author : Ruoqi Wang; John Leander; Raid Karoumi; Boulent Imam; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fatigue; steel bridges; decision-making; reliability analysis; risk analysis; spatial correlation; system modelling; inspection and maintenance; Utmattning; stålbroar; beslutsfattande; tillförlitlighet; riskanalys; rumslig korrelation; systemmodellering; inspektion och underhåll; Bro- och stålbyggnad; Structural Engineering and Bridges;

    Abstract : Fatigue is one of the primary reasons that limit the service life of steel bridges. Many bridges in Sweden and other countries have progressively approached their anticipated service lives. Since funding and resources are limited, simultaneously replacement or maintenance of bridges is impractical. READ MORE

  7. 5. Life cycle behaviour of concrete bridges : laboratory test and probabilistic evaluation

    Author : Markus Bergström; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Abstract : The structural life for a concrete structure located in an environment where corrosion is promoted by humidity or chlorides from sea or de-icing salt could in general be described in the following manner. The structure is manufactured and is at that point considered to be intact. READ MORE
