  1. 1. The use of higher steel grades in building elements

    Master-uppsats, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Hampus Berggren; [2021]
    Nyckelord :Area reduction; Change of steel grade; Emission reduction; High strength steel; Higher steel grade; Steel;

    Sammanfattning : Structural steel is one of the main building materials used commercial. Its strength is its formality and high yield strength which allows less material overall. Steel is often divided into steel grades such as S275, S355, S420 and so forth. LÄS MER

  3. 2. Undertray Design and Development Procedure with CFD : An Optimization Study of Different UndertrayDesigns with CFD Computations

    Master-uppsats, KTH/Strömningsmekanik och Teknisk Akustik

    Författare :Aaron Poutiainen; [2021]
    Nyckelord :;

    Sammanfattning : Race car aerodynamics has played a vital part to improve lap times over the years of motor racing. Having good road adhesion with slick tires and aerodynamic downforce will increase the vehicles maximum lateral force and thus higher cornering speeds can be achieved. LÄS MER

  4. 3. A pre-study of the static behaviour of a single diagonal timber arch bridge

    Master-uppsats, KTH/Byggnadsmaterial

    Författare :Lovisa Öhgren; Malin Åström; [2020]
    Nyckelord :timber; single diagonal arch bridge; arch bridge; buckling; RFEM; deformation; ultimate limit state; serviceability limit state;

    Sammanfattning : The aim of this thesis is to study and gain more insight about the static behaviour of the three hinged single diagonal timber arch bridge in different situations. The bridge was tested for static analyses for both Ultimate Limit State and Serviceability Limit State, to investigate its behaviour and if it is possible to be built at the selected location.

  5. 4. High Temperature Tribology in Hot Stamping

    Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Evan Kurnia; [2019]
    Nyckelord :high temperature tribology; hot stamping; acoustic emission; condition monitoring; hardfacing;

    Sammanfattning : Many automotive components are made of Al-Si coated ultra-high strength boron steel (UHSS) and are produced by hot stamping process. In this process, the workpiece is heated to an austenitizing temperature and is then formed and quenched simultaneously between the tools to achieve the desired shape and high strength. LÄS MER

  7. 5. Analysis of post-tensioned concrete box-girder bridges : A comparison of Incremental launching and Movable scaffolding system

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :Hamad El Hamad; Furkan Tanhan; [2018]
    Nyckelord :Movable scaffolding system; MSS; Incremental launching; post-tension; prestress; slen- derness; box-girder; Stockholm Bypass; Movable scaffolding system; MSS; Etappvis lansering; efterspänning; förspänning; slankhet; box-girder; Förbifart Stockholm;

    Sammanfattning : When designing a bridge it is of high importance that the geometry for the cross section is optimized for the structure. This is partly due to the influence of the amount of material needed and its impact on the budget and environment. LÄS MER
