  1. 1. FE-Modelling of Composite Girder tests

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

    Author : Holger Berggren; Bergstedt Ola; [2024]
    Keywords : shear connector; post-installed; coiled spring pins; composite girder; partial composite action; finite element method;

    Abstract : Many of the existing steel-concrete bridges may need to be strengthened, as heavier vehicles areallowed on the Swedish roads. These bridges could possibly be strengthened by post-installingshear connectors. The shear connectors may enhance the load-bearing capacity through a higherdegree of composite action between the steel and concrete interface. READ MORE

  2. 2. 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. 3. Non-Linear FE-Analysis of a Composite Action Girder with Coiled Spring Pins as Shear Connectors

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

    Author : Simon Stahlin; [2019]
    Keywords : composite bridge; composite action; shear connector; coiled spring pins; finite element modeling; samverkansbro; samverkan; skjuvförbindare; spiralbult; finita element modellering;

    Abstract : For bridges to cope with increased requirements such as increased loads, strengthening work can be carried out. In cases where older steel-concrete bridges do not have a composite action, an alternative is to create composite-action to achieve a higher flexural strength. It is introduced by post-installing shear connectors. READ MORE

  4. 4. Numerical analysis and model updating of a steel-concrete composite bridge : Parametric study & Statistical evaluation

    University essay from KTH/Bro- och stålbyggnad

    Author : Keiwan Abdulrahman; Fadi Potrus; [2015]
    Keywords : Model updating; Finite element method; Parameter study; Abaqus; Composite bridges; Global behaviour; Modeluppdatering; Finita element metoden; Parameter studie; Abaqus; Samverkansbroar i stål och betong; Globalt beteende;

    Abstract : In the year 2006, only 10 years after the steel- concrete composite bridge, Vårby bridge was built, fatigue cracks were found during an inspection. To further investigate the reasons and the potential danger of the cracks, an investigation under the commission of the Swedish Transport Administration was issued in 2009. READ MORE

  5. 5. Temporary formworks as torsional bracing system for steel-concrete composite bridges during concreting of the deck

    University essay from Lunds universitet/Avdelningen för Konstruktionsteknik; Lunds universitet/Väg- och vattenbyggnad (CI)

    Author : Andreas Winge; [2014]
    Keywords : temporary formworks; stabilizing; concreting; bracing; bridge girders; Technology and Engineering;

    Abstract : A critical stage for the construction of steel-concrete composite bridges occurs during casting of the bridge deck, when the wet concrete has still not hardened. The entire construction load is then taken by the non-composite steel sections. READ MORE
