  1. 21. Fatigue and dynamics of secondary beams in steel railway bridges

    University essay from KTH/Bro- och stålbyggnad

    Author : Peeter Kanter; [2014]
    Keywords : Bridge; Fatigue; Assessment; Dynamics;

    Abstract : Many steel railway bridges in Europe are older than 50 years whilethey are subjected to higher loads than they were originally designedfor. As many of these bridges are approaching the end of their designlife it is crucial to carry out accurate fatigue assessments in order toensure their safety and keep them in service. READ MORE

  3. 22. Fatigue life assessment of potential weld improvement techniques using 3D fracture analysis

    University essay from KTH/Lättkonstruktioner

    Author : Nikola Mrdjanov; [2014]
    Keywords : ;

    Abstract : This thesis work was done in conjunction with the VINNOVA-funded research and development project LIGHTSTRUCT. It was performed in the department of lightweight structures at KTH. The thesis investigated two potential weld improvement techniques called toe weaving and extended leg. READ MORE

  4. 23. Virkesflöde och val av hjulsystem på virkesfordon inom Region Iggesund, Holmen Skog

    University essay from SLU/Dept. of Forest Resource Management

    Author : Carl Rådström; [2014]
    Keywords : virkesflöde; vägstandard; tillgänglighet; transportavstånd; transportteknik; transportkostnad;

    Abstract : Syftet med detta arbete har varit att undersöka hur virkesflödet från Region Iggesund varierar under året och belysa orsakerna till detta samt att beräkna transportkostnader och analysera vilka distrikt som skulle kunna ha störst nytta av virkesfordon med Central Tyre Inflation (CTI) eller Super Singel hjul, alternativt hjulsystem som kombinerar de båda teknikerna. Utgångspunkten har varit rationell virkesförsörjning från skog till industri, med så låga virkeslager och transportkostnader som möjligt. READ MORE

  5. 24. Load Effect Modelling in Fatigue Design of Composite Bridges : An assessment of Fatigue Load Models 3, 4 and 5 according to SS-EN-1991-2 Actions on Structures – Part 2: Traffic loads on Bridges

    University essay from KTH/Stålbyggnad

    Author : Mathias Dahlvik; Johan Eriksson; [2014]
    Keywords : Fatigue; Composite Bridges; Eurocode; BRO 2004; Fatigue Load Model; FLM; utmattning; kompositbroar; Eurokod; BRO 2004; utmattningslastmodell; FLM;

    Abstract : At the turn of 2010/2011, Sweden went from designing structures according to nationaldesign codes to the new European standards Eurocode. For bridge engineers, this implieda change from a combination of BRO 2004 and BSK 07 to the Eurocode as the maindocuments, complemented by national documents such as TRVK Bro 11. READ MORE

  6. 25. Statistical Assessment of Uncertainties Pertaining to Uniaxial Vibration Testing and Required Test Margin for Fatigue Life Verification

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Davood Dehgan Banadaki; Sunay Sami Durmush; Sharif Zahiri; [2013]
    Keywords : Vibration Testing; FEA; Natural Frequency; Deterministic and Random Vibrations; Fatigue;

    Abstract : In the automotive industry uniaxial vibration testing is a common method used to predict the lifetime of components. In reality truck components work under multiaxial loads meaning that the excitation is multiaxial. A common method to account for the multiaxial effect is to apply a safety margin to the uniaxial test results. READ MORE
