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. 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

4. 3. Railway bridges with floating slab track systems : Numerical modelling of rail stresses - Dependence on properties of floating slab mats

   University essay from Luleå tekniska universitet/Byggkonstruktion och -produktion

   Author : Daniel Kostet; [2018]
   Keywords : ballasted track; bridge; elastic mat; expansion; finite element method FEM ; finite element analysis FEA ; floating slab mat; interaction; International union of railways UIC ; non-ballasted track; SOFiSTiK; ballasterat spår; ballastfritt spår; bro; dilatationsfogar; finita elementmetoden FEM ; finit elementanalys FEA ; fixerat spår; interaktion; Internationella järnvägsunionen UIC ; SOFiSTiK; vibrationer; vibrationsdämpande matta;

   Abstract : The increased use of continuously welded rails in the railway systems makes it necessary to increase the control of the rail stresses to avoid instability and damages of the rails. Large stresses are especially prone to appear at discontinuities in the railway systems, such as bridges, due to the interaction between the track and the bridge. 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. 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
