  1. 16. Fatigue evaluation of welded details – using the finite element method

    Author : Mustafa Aygül; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; the finite element method; welded details; effective notch stress method; Hot-spot stress method; fracture mechanics;

    Abstract : The fatigue evaluation of welded details is generally based on the notion of nominal stress, using the classified S-N curves with corresponding fatigue classes for typical details. An approach of this kind should be used with extra caution to ensure that the load effects for components are accurately captured, because an ever-increasing number of welded details are resulting in a limited number of possible treatable design cases.

  4. 19. Towards Sustainable Construction: Life Cycle Assessment of Railway Bridges

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Guangli Du; Raid Karoumi; Håkan Sundquist; Helge Brattebo; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Life cycle assessment; LCA; Environment; Railway Bridge; Sustainability; Järnvägsgruppen - Infrastruktur; Järnvägsgruppen - Infrastruktur;

    Abstract : Since last few decades, the increased pressure from the environmental issues of natural resource depletion, global warming and air pollution have posed a great challenge worldwide. Among all the industrial fields, bridge infrastructures and their belonged construction sector contribute to a wide range of energy and raw materials consumptions, which is responsible for the most significant pollutions.

  5. 20. Capacity assessment of arch bridges with backfill Case of the old Årsta railway bridge

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Andreas Andersson; Håkan Sundquist; Raid Karoumi; Clive Melbourne; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Concrete arch bridge; soil backfill; spandrel walls; field measurements; finite element method; load distribution; ultimate limit state.; Betongbågbro; jordfyllning; sidomur; fältmätningar; finita element metoder; lastspridning; brottgränstillstånd.; TECHNOLOGY Civil engineering and architecture; TEKNIKVETENSKAP Samhällsbyggnadsteknik och arkitektur;

    Abstract : The work presented in this thesis comprises the assessment of existing arch bridges with overlying backfill. The main objective is to estimate the load carrying capacity in ultimate limit state analysis. A case study of the old Årsta railway bridge is presented, serving as both the initiation and a direct application of the present research. READ MORE
