  1. 1. Analysis of combined response of railway bridge and track : A parametric finite element model of the bridge across Bryngeån

    University essay from KTH/Bro- och stålbyggnad

    Author : Moa Nolinder; [2023]
    Keywords : ;

    Abstract : When designing a railway bridge it is common to consider and designthe bridge structure and the track structure separately. However, theyare connected and that interaction generates a combined response and aforce transfer between them. READ MORE

  3. 2. Dynamic Analysis of Portal Frame Bridges for High-Speed Trains : A Parametric Study

    University essay from KTH/Bro- och stålbyggnad

    Author : Antonio Dib; Ramayana Salgado; [2023]
    Keywords : ;

    Abstract : A high-speed railway network is important for Sweden’s development. However, anincreasing train speed brings new challenges in bridge design due to higher bridgeaccelerations. READ MORE

  4. 3. Evaluation of load distribution on ballasted reinforced concrete railway trough bridges

    University essay from Luleå tekniska universitet/Byggkonstruktion och brand

    Author : Alex Eriksson; [2023]
    Keywords : Concrete; numerical analysis; trough bridge; railway bridge; finite element model; discrete element method; Betong; numeriskanalys; trågbro; tågbro; finita elementmetoden; diskreta elementmetoden;

    Abstract : A significant portion of the reinforced concrete railway bridges in Sweden are reaching their designed lifespan and are scheduled to be demolished and replaced in the upcoming years. To limit the econom-icand environmental impact related to the replacement of existing railway infrastructure, a comprehen-siveevaluation of their capacity is required with the aim of extending its lifespan.

    Abstract : I Sverige står byggsektorn för 25% av landets totala utsläpp av växthusgaser, där material står för mer än hälften av dessa utsläpp [1][2][3]. De största bidragsgivarna är stål och betong, men även material som aluminium och asfalt har en betydande miljöpåverkan. READ MORE

  6. 5. Improved Bridge Load Capacity via Dynamic Train-Track-Bridge Interaction : Assessing the dynamic amplification factor caused by measured track irregularities for rail freight transport

    University essay from KTH/Bro- och stålbyggnad

    Author : Muhannad Asaad; [2023]
    Keywords : ;

    Abstract : The carbon impact of transportation is large and requires sustainable solutions. With expected population growth, rail transportation plays a vital role in facilitating a greener Europe. The expansion of the rail infrastructure is therefore of essential importance for future challenges. READ MORE
