  1. 1. Optimal Design of Bridges for High-Speed Trains : Single and double-span bridges

    University essay from KTH/KTH/Bro- och stålbyggnadJärnvägsgruppen, JVG

    Author : Carine Mellier; [2010]
    Keywords : Optimization; Vertical deck acceleration; Railway bridges; High-speed trains; Train Signature; Finite element analysis;

    Abstract : To deal with an increasing demand in transportation, trains are made longer and faster. Higher speeds imply higher impacts on bridges. Therefore, structures have to be designed to resist these new constraints. The Eurocode (2002) introduced additional checks for the design of high-speed railway bridges. READ MORE

  3. 2. Capacity assessment of a single span arch bridge with backfill : A case study of the Glomman Bridge

    University essay from KTH/Byggvetenskap; KTH/Byggvetenskap

    Author : Henrik Bjurström; Johan Lasell; [2009]
    Keywords : Arch bridge; vault; finite element; backfill; failure envelope; masonry; capacity assessment; Bågbro; valv; finita element; fyllning; brottenvelopp; stenvalv; klassningsberäkning;

    Abstract :  The aim of this Master Thesis is to assess the load carrying capacity of the Glomman Bridge outside of the Swedish city Örebro. The Glomman Bridge is an unreinforced concrete single span arch bridge with backfill. The bridge was constructed in 1923 on assignment from the Swedish National Railways (SJ). READ MORE

  4. 3. Vertical Displacements in a Medium-rise Timber Building : Limnologen in Växjö, Sweden

    University essay from Växjö universitet/Institutionen för teknik och design; Växjö universitet/Institutionen för teknik och design; Växjö universitet/Institutionen för teknik och design

    Author : Xiong yu Zeng; Su Xin Ren; Sabri Omar; [2009]
    Keywords : Limnologen; Vertical Displacement; Timber Building; Finite Element Analysis; Limnologen; Vertikalförskjutningar; Träkonstruktion; FEM;

    Abstract : Träbyggnandet i Sverige gick in i en ny era när myndigheterna beslutade att upphäva förbudet mot att bygga byggnader som är högre än två våningar. Denna förändring i lagstiftningen har bidragit till att utveckla träbyggandet under det senaste decenniet. READ MORE

  5. 4. Numerical simulations of the plastic deformation of insulating joints

    University essay from Chalmers tekniska högskola/Institutionen för tillämpad mekanik

    Author : Johannes Gunnarsson; [2009]
    Keywords : Insulating rail joint; plastic deformation; ratchtetting; low-cycle fatigue; inclined joint; hyper-elastic material;

    Abstract : Numerical simulations were carried out to evaluate the performance of insulating joints in railway tracks. Although insulating joints are considered weak spots on the track due to the imposed rail discontinuity, they are nevertheless essential to monitor and control train traffic. READ MORE

  6. 5. Modeling of the interfacial heat flow in a single-belt
    casting simulator

    University essay from Luleå/Tillämpad fysik, maskin- och materialteknik

    Author : Fredrik Nääs; [2009]
    Keywords : inverse heat conduction; heat flow;

    Abstract : Strip casting is a common, low-cost method to cast thin aluminum sheets at gauges close to the final product gauge. Since this process involves fewer steps than traditionally casting methods, the manufacturing time for aluminum products is reduced considerably. Usually, when surface defects occur during the casting process, the slab is scalped. READ MORE
