  2. 6. Analysis of traffic load effects an railway bridges

    Author : Gerard James; KTH; []
    Keywords : bridge; rail; traffic load. Load effect. Dynamic amplification factor; extreme value theor; peaks-over-threshold;

    Abstract : The work presented in this thesis studies the load and loadeffects of traffic loads on railway bridges. The increasedknowledge of the traffic loads, simulated using fieldmeasurements of actual trains, are employed in a reliabilityanalysis in an attempt at upgrading existing railwaybridges. READ MORE

  4. 7. Ice load prediction for design of ice-going ships for inland waterways

    Author : Meng Zhang; Karl Garme; Magnus Burman; Malin Åkermo; Pentti Kujala; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; inland waterway ship; ice load; ice conditions; ice properties; FSICR; probabilistic method; ice-hull interaction; numerical model; structural response; finite element analysis; Engineering Mechanics; Teknisk mekanik;

    Abstract : With increasing interest in utilizing the inland waterways (IWW) in European countries, the design of IWW vessels gains attention both from a transport efficiency and an emission control point of view. However, unlike in western and central European countries, in Nordic countries, e.g. READ MORE

  5. 8. Load-carrying capacity of a strengthened reinforced concrete bridge : Non-linear finite element modeling of a test to failure. Assessment of train load capacity of a two span railway trough bridge in Örnsköldsvik strengthened with bars of Carbon Fibre Reinforced Polymers (CFRP)

    Author : Arto Puurula; Mario Plos; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Abstract : To meet the future traffic demands there is a constant need of making the infrastructure moreeffective. This can be achieved by increasing the capacity and/or life length of traffic lines. READ MORE

  6. 9. Thermal stresses in load-bearing glass-timber components

    Author : Karin Lundstedt; Erik Serrano; Ola Dahlblom; Linnéuniversitetet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Thermal stresses; thermal failure; glass and wood construction; incident solar radiation; shading; cracks; temperature difference; finite element method.; Technology byts ev till Engineering ; Teknik;

    Abstract : Thermal stresses can arise in glass used in architectonic realisations in buildings as a result of solar irradiation:  that is, sunlight.  The magnitude of these thermal stresses depends on the temperature conditions in the glass in terms of the temperature differences between warm and cold areas.

  7. 10. Voltage Stability Simulations Using Detailed Models Based on Field Measurements

    Author : Daniel Karlsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; capacity limits; field measurements; dynamic load models; on-load tap-changer control system; voltage stability; simulations;

    Abstract : This dissertation deals with voltage stability simulations, including dynamic load models, on-load tap-changer control system dynamics and generator reactive power output capacity limits. The simulations are based on sequential solving of ordinary load flow cases augmented with dynamic models. READ MORE
