  1. 11. Strengthening of non-composite bridges by Partial Composite Action

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Johan Tjernberg; [2022]
    Keywords : Composite action; Composite bridges; Partial shear connection; Partial Composite Action; Shear connectors; Coiled Spring Pins;

    Abstract : A common bridge type is the steel-concrete bridge where the concrete deck is built over steel girders. In many earlier designs the bridge type was often built as non-composite, which means that the concrete deck and the steel girder has no shear connection at the steel-concrete interface and therefore bend as individual components.

  3. 12. Expansion Joints in timber bridges : Mechanical behavior under external loading

    University essay from Linnéuniversitetet/Institutionen för byggteknik (BY)

    Author : Johan Gustafsson; Jakob Myhrberg; [2021]
    Keywords : Expansion joint; FE-modeling; Timber bridges; Steel-to-wood connections; European Technical Approval Guidelines;

    Abstract : To design a bridge, different typologies of construction materials can be used. All materials have in common that deformations occur due to different events, such as externalloading, temperature- and moisture variations. To allow these kinds of deformations,Expansion Joints (EJs) are used in the structure. READ MORE

  4. 13. Concrete reinforced with FRP rebars : Evaluation of durability and behaviour in the Service Limit State (SLS)

    University essay from Luleå tekniska universitet/Byggkonstruktion och brand

    Author : David Ottosson; [2021]
    Keywords : GFRP; Durability; SLS; Atena;

    Abstract : One of the most common building materials is concrete and it has been for a long time. To overcome its low tensile capacity concrete structures are normally reinforced with steel rebars. READ MORE

  5. 14. Modelling Time-Dependent Effects for Segmentally Constructed Prestressed Concrete Bridges

    University essay from Lunds universitet/Avdelningen för Konstruktionsteknik; Lunds universitet/Institutionen för bygg- och miljöteknologi

    Author : Niclas Elfving; Joel Sunesson; [2021]
    Keywords : Concrete; Creep; Segmentally constructed; Prestressing; Post-tensioning; Viscoelastic; Eurocode; Finite Element; Shell elements; Beam elements; Time-dependant; Steel relaxation.; Technology and Engineering;

    Abstract : Tidsberoende effekter, såsom krypning, krympning och stålrelaxation, är ofta svåra att prediktera när det kommer till förspända betongkonstruktioner. Krypning som ett fenomen är komplicerat och förenklas därför i gällande byggnormer (Eurocode), för att underlätta konstruktörens arbete. READ MORE

  6. 15. Cost optimization of composite bridges

    University essay from KTH/Bro- och stålbyggnad

    Author : Markus Lythell; Jonathan Stenberg; [2020]
    Keywords : Composite bridge; Optimization algorithm; Pattern search; Cost optimization; MATLAB; Samverkansbroar; Optimeringsalgoritmer; Pattern search; Kostnadsoptimering; MATLAB;

    Abstract : Today in most design offices the practice when designing infrastructure is to adopt a trial-and-error based approach. This means that one solution to the problem is evaluated and based on the results the design is altered. This process is then repeated until satisfactory results have been achieved. READ MORE
