3. 2. Capacity assessment of arch bridges with backfill : Case of the old Årsta railway bridge

   Författare :Andreas Andersson; Håkan Sundquist; Raid Karoumi; Clive Melbourne; KTH; []
   Nyckelord :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.; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur;

   Sammanfattning : 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. LÄS MER

4. 3. Soil-Steel Composite Bridges : Research advances and application

   Författare :Amer Wadi; Raid Karoumi; Lars Pettersson; Ian D. Moore; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flexible culvert; Soil‒steel composite bridge; Sloping terrain; Swedish design method; Finite element model; Ultimate capacity; Avalanche load; Failure load; Low soil cover; Failure mechanism; Long-span; Byggvetenskap; Civil and Architectural Engineering;

   Sammanfattning : Soil-steel composite bridges are considered competitive structures being an economical alternative to similar span concrete bridges. This frequently stimulates practitioners to push their design limits and expand the different areas of application including their performance in sloping terrain. LÄS MER

5. 4. Stress-laminated-timber bridge decks subjected to ultimate loads

   Författare :Kristoffer K J Ekholm; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ultimate-load tests; Stress-laminated timber; Timber bridges;

   Sammanfattning : Stress-laminated-timber (SLT) bridge decks are a satisfactory alternative to conventional short-span bridges in terms of cost and performance. SLT decks are made from several deck laminations positioned side by side. LÄS MER

7. 5. 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)

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

   Sammanfattning : 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. LÄS MER
