  1. 1. 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

  3. 2. Finite Element Analysis of the Dynamic Effect of Soil-Structure Interaction of Portal Frame Bridges - A Parametric Study

    University essay from KTH/Bro- och stålbyggnad

    Author : Turgay Dagdelen; Shaho Ruhani; [2018]
    Keywords : Soil-Structure Interaction; Railway Bridge; Portal Frame Bridge; Dynamic Analysis; Parametric Study; Nonlinear Analysis; Jord-struktur interaktion; Järnvägsbro; Plattrambro; Dynamisk analys; Parametrisk studie; Icke-linjär analys;

    Abstract : In Sweden, the railway sector currently faces the challenge of developing its first high-speed railway line, in response to the need to provide faster domestic and international transport alternatives. High-speed train passages on railway bridges can cause resonance in the bridge superstructure, which induce high accelerations that should not exceed the limits stipulated in the current design code.

  4. 3. Landskapet i samband med infrastrukturprojekt : med fokus på utvecklingen av Sveriges höghastighetsjärnväg

    University essay from SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Author : Emelie Hansén; [2017]
    Keywords : höghastighetsjärnväg; Ostlänken; landskap; infrastrukturutveckling; fragmentering; barriärer; restyta;

    Abstract : Utvecklingen av höghastighetsjärnvägen i Sverige förväntas medföra omfattande effekter på landskapet. Det kommer ske en strukturförändring som innebär nya, stora barriärer. Tillsammans med befintligt infrastrukturnätverk fragmenteras landskapet ytterligare och allt mindre ytor skapas, som kan kallas restytor. READ MORE

  5. 4. High-speed railway embankments : a comparison of different regulation

    University essay from KTH/Jord- och bergmekanik

    Author : Angelica Alamaa; [2016]
    Keywords : High-speed; railway; embankments;

    Abstract : Swedish transport administration initiated this Master Thesis project and the aim was to compare regulations for the design of high-speed railways from three European countries: France, Germany and Spain. The reason why this is of interest for the Swedish transport administration is the design of the first Swedish high-speed railway, called Ostlänken. READ MORE

  6. 5. The effect of increasing train lengths on the fatigue lifespan of a bridge.

    University essay from KTH/Bro- och stålbyggnad

    Author : Franck Monballiu; Wouter Schils; [2016]
    Keywords : Finite element model updating; sensitivity analysis; objective function; dynamic analysis; Banafjäl bridge; fatigue lifetime; high-speed bridge;

    Abstract : More and more pressure is exerted on railway infrastructure due to an increasing transportation demand and population density. Instead of expanding the net, a possible solution could lie in the enlargement of the capacity by operating longer trains rather than more short ones. READ MORE
