  1. 1. Trycksatta Stigarledningar : En utvärdering av SBF 504:1

    Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Gustav Lundberg; Filip Aronsson; [2022]
    Nyckelord :Brandingenjör; Stigarledningar;

    Sammanfattning : In a society where it is becoming increasingly common to build on height, it is important that rules and regulations regarding fire protection are adhered to. Boverket introduced in BBR 19 (BFS 2011:6) that buildings with a building height of more than 40 meters should be designed with pressurized riser lines. LÄS MER

  3. 2. Design optimization for obtaining zero defects in steel casting

    Master-uppsats, Högskolan i Jönköping/JTH, Material och tillverkning

    Författare :Pranit Pramod Purkar; [2019]
    Nyckelord :Casting; Defects; Gating System; Molten Metal; Mould; Simulation;

    Sammanfattning : This thesis is about the design of the gating system and selection of proper alloy for defects free (grate bar) casting. The gating system plays an important role in casting manufacturing process. The gating system has different elements like pouring cup, sprue, well, runner, riser, and ingates. LÄS MER

  4. 3. Building occupant movement in wide descending stairs

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Martha Ålgård; [2017]
    Nyckelord :Descending stairs; occupant movement; wide stairs; handrails; Technology and Engineering;

    Sammanfattning : Several incidents in the past confirm that crowd movement in stairs represents a risk that has potential of causing serious injuries. Extensively research has been conducted for descending stairs. However, less is known about particularly wide staircases, which is taken to be stairs with tread width of 1.2m or above. LÄS MER

  5. 4. J-tube Pull-In of Rigid Risers.

    Magister-uppsats, KTH/Hållfasthetslära (Inst.)

    Författare :Orkhan Huseynov; Gregor Gregorsson; [2015]
    Nyckelord :;

    Sammanfattning : This work covers an advanced finite element analysis (FEA) approach of investigating riser pull-in through an existing J-tube up to an offshore platform. A riser is a vertically oriented piping used to deliver fluid, gas or other relevant packages upward. LÄS MER

  7. 5. Utslagningsmetoder för trappor – en jämförande studie

    Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvård
