  1. 1. The influence of torsional resistance of the deck on the dynamic response of a high-speed railway bridge : Case study: Ulla River Viaduct

    University essay from KTH/Bro- och stålbyggnad

    Author : Claudia Sanroman Cervero; [2017]
    Keywords : Dynamics; High-speed railway bridges; Torsional rigidity of the deck; FE modelling; 3D Model; Ulla River Viaduct;

    Abstract : Understanding how different parameters affect the dynamic response of high-speed railway bridges is crucial to selecting an efficient structural form. Despite existing numerous publications within this field, only few address the importance of torsional deformations. READ MORE

  2. 2. An MMC-based topology with Dual-Active-Bridge power channels for load balancing in 50 Hz-railway applications

    University essay from KTH/Skolan för elektro- och systemteknik (EES)

    Author : Andreas Zafeiropoluos; [2017]
    Keywords : Power electronics; STATCOM; MMC; power channel; power quality; negativesequence compensation; high-speed trains;

    Abstract : The purpose of this thesis report is to investigate challenges related to railway electrification. Inac-railway systems, trains are most often single-phase loads, which can create significantunbalances in the grid, when fed directly from two adjacent phases. READ MORE

  3. 3. Comparison of ballasted and ballastless bridges for high speed trains

    University essay from KTH/Bro- och stålbyggnad; KTH/Bro- och stålbyggnad

    Author : David Matos Sánchez; Maša Nikolic; [2016]
    Keywords : High-speed train; concrete bridge; beam bridge; dynamic; 3D dynamic;

    Abstract : The purpose of the project is to investigate the difference in performance betweenballasted and ballastless railway bridges dedicated to high speed trains by taking intoaccount both static and dynamic requirements. The main questions are:a) whether choosing a ballastless bridge results in a more slender section due tothe lower self-weightb) if the design of bridges for high speed trains is governed by the static or by thedynamic requirements.

  4. 4. Väsmans strandband : gestaltningsförslag för en hållbar och tillgänglig aktivitetspark i Ludvika

    University essay from SLU/Dept. of Urban and Rural Development

    Author : Kajsa Holmqvist; [2016]
    Keywords : aktivitespark; lek; aktivitet; tillänglighet; hållbarhet; karaktär; Ludvika; band;

    Abstract : Detta examensarbete handlar om att skapa en plats där människor vill vistas och får möjlighet att röra på kroppen. På uppdrag av Ludvika kommun presenteras ett övergripande gestaltningsförslag för en aktivitetspark vid utvecklingsområdet Väsmanstrand i Ludvika. READ MORE

  5. 5. Dynamic Soil-structure Interaction of Portal Frame Bridge Walls for High-speed Railways

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

    Author : Henrik Malm; [2016]
    Keywords : SSI; Soil-structure interaction; Structural dynamics; High-speed railway bridges; Impedance; Receptance; Finite element method; Portal frame bridge; Technology and Engineering;

    Abstract : In Sweden, high-speed railways is a subject for public debate. The first stage of a high-speed train network, Ostlänken between Stockholm and Linköping, is under investigation, and is planned to be trafficked in 2028. The high-speed railway is intended to hold traffic with speeds up to 320 km/h. READ MORE
