  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. A 3D Sliding Bearing Finite Element Based on The Bouc-Wen Hysteretic Model : Mathematical modelling and numerical implementation

    University essay from KTH/Bro- och stålbyggnad

    Author : Sicong Wei; [2020]
    Keywords : high-speed railway; nonlinear dynamics; bridge bearings; friction; hysteresis; secondary development; damping;

    Abstract : Bridge bearing is an essential component with the function of connecting the superstructure and substructure of the bridge, transmitting load and providing movability to the superstructure. Under dynamic conditions, the internal friction of bridge bearing dissipates the vibration energy and therefore reduces the dynamic response of the bridge. READ MORE

  4. 3. A 3D sliding bearing finite element based on the Bouc-Wen model : Implementation in Abaqus

    University essay from KTH/Bro- och stålbyggnad

    Author : Rémi Lantoine; [2020]
    Keywords : Railway bridge; dynamics; resonance; sliding bridge bearings; finite element; Abaqus; friction; steel; Teflon; PTFE; Bouc-Wen model; friction coefficient; temperature; heating;

    Abstract : As rail transportation is significantly more virtuous than airplanes or cars in terms of greenhousegases emissions, its development is being encouraged in several European countries, includingSweden. In addition, the development of railway lines on which trains can travel at higher speeds ismade in Sweden with the integration of existing infrastructure. READ MORE

  5. 4. Dynamic Design of Bridges on High-Speed Railway Lines

    University essay from Lunds universitet/Institutionen för byggvetenskaper; Lunds universitet/Byggnadsmekanik

    Author : Felicia Nilsson; Filippa Dahl; [2019]
    Keywords : High-speed railway bridges; bridge-train resonance; structural dynamics; modal dynamics; time stepping; soil-structure interaction; finite element method; BRIGADE Plus; Technology and Engineering;

    Abstract : In recent years, high-speed railway has been on the upswing in the public debate, as Swedish authorities have affirmed the plans of a high-speed corridor connecting Stockholm, Gothenburg and Malm¨o. The track speed limit is not fully determined, but will be in the range of 250-320 km/h. READ MORE

  6. 5. A Simulation of the Millau Viaduct

    University essay from KTH/Mekanik

    Author : Cathrina Bergsjö; Marcus Pettersson; [2016]
    Keywords : ;

    Abstract : Cable-stayed bridges have become very popular over the last ve decades due totheir aesthetic appeal, structural eciency, the limited amount of material usageand nancial benets. The rapid increase of new techniques creating longer spans,slender decks and more spectacular design has given rise to a major concern ofthe dynamic behavior of cable-stayed bridges. READ MORE
