  1. 1. RC Trough Bridges: A Parametric Study using FEM and an Analysis of their Current State

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

    Author : David Åkergren; [2021]
    Keywords : concrete; trough bridges; parametric study; FEM; BaTMan; ATENA; load eccentricity; compressive strength; tensile strength;

    Abstract : There are approximately 4000 railway bridges in Sweden managed by the Swedish Administration of Transport (Trafikverket), of which a common construction type is the reinforced concrete (RC) trough bridge, which is a structure that consists of a slab carried by two longitudinal main beams which transfer loads towards the supports. A substantial amount of the RC trough bridge population is approaching the end of their service lives which consequently implies that the replacement of some of these bridges can be expected in the near future.

  3. 2. 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

  4. 3. Dimensioning of slabs for high-speed railway lines

    University essay from Linnéuniversitetet/Institutionen för byggteknik (BY)

    Author : Marcus Mohlén; Jesper Malmberg; Filip Hahrs; [2016]
    Keywords : Concrete slab track design; High-speed railway lines; Beton Kalender 2000; Westergaard;

    Abstract : The Swedish Transport Administration has been giving the task to set up a new standard for concrete slabs for the new high-speed railway in Sweden. They are demanding that the concrete slabs must be dimensioned according to the German Beton Kalender 2000. READ MORE

  5. 4. Evaluation of a Tramway’s Track Slab in Conventionally Reinforced Concrete or Steel Fibre Concrete

    University essay from KTH/Betongbyggnad

    Author : Stavros Zioris; Alija Vranjkovina; [2015]
    Keywords : Steel fibre reinforced concrete SFRC ; conventional reinforcement; finite element;

    Abstract : The dominant reinforcement used widely for concrete structures is conventional steel bars (rebars). Nevertheless, the perpetual effort toward evolution and development could not exclude the engineering field, thus new innovative and sophisticated methods are introduced. READ MORE
