  1. 1. Forcerad uttorkning av plattans voter : Hur man möjliggör snabbare hydratation av fukt

    Uppsats för yrkesexamina på grundnivå,

    Författare :Rasmus Lennartsson; Johannes Gunnarsson; [2022]
    Nyckelord :Concrete; moisture; w c; Betong; vattencementtal; hållfasthet; PPB; TorkaS; fukt; uttorkning.;

    Sammanfattning : With a goal to be able to cast a concrete slab and to dry out the moisture in the concrete in a faster way. To meet the requirement for certification of green building construction, the concrete slab must be dried out to an approved level before it is covered with a flooring material. LÄS MER

  3. 2. A comparative evaluation of hydrostatic pressure and buckling of a large cylindrical steel tank designed according to EN14015 and according to the Eurocodes

    Master-uppsats, Linnéuniversitetet/Institutionen för byggteknik (BY)

    Författare :Musole Kambita; [2022]
    Nyckelord :Cylindrical steel tanks; yield strength; carbon steel; high strength steel; design load; buckling; stiffening rings; Finite Element Method FEM ; Linear Elastic Bifurcation LBA ; and Geometrically and Materially Nonlinear Analysis with Imperfections GMNIA .;

    Sammanfattning : Above ground steel storage tanks are used worldwide for the storage of various liquids. EN 14015:2005, which has traditionally been used to design the tanks, does not necessarily fulfil the requirements of the Swedish Building Code. LÄS MER

  4. 3. Investigation of methods to analyse global stability of a reinforced concrete stabilising core

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :Evelina Husak; Ellinor Persson; [2022]
    Nyckelord :;

    Sammanfattning : Ensuring the structural stability of a building is an evident requirement for the building to be safe to use. This becomes a qualified task for a structural engineer. Ensuring stability has become especially important nowadays while stabilising elements often are kept to a minimum and tall buildings are common. LÄS MER

  5. 4. Strukturella förbättringar av en markstabiliseringsmast

    Master-uppsats, Mälardalens högskola/Akademin för innovation, design och teknik

    Författare :Axel Skog; [2021]
    Nyckelord :ANSYS; FEA; SpaceClaim; SolidWorks; Jet-Grouting; Camatec; Scandinavian Pile Driving; ground stabilization; CAE; CAD; ANSYS; FEM; SpaceClaim; SolidWorks; Jet-Grouting; Camatec; Scandinavian Pile Driving; markstabilisering; CAE; CAD;

    Sammanfattning : This report has examined the possibilities of stiffening and strengthening a ground stabilization mast, in a way that a small production company can manufacture. The soil stabilization technique in question is Jet-Grouting also called injection drilling, which involves drilling to the desired depth and then letting high-pressure water jets mixed with filling mass to erode the surrounding soil mass and form pillars below the ground surface.

  7. 5. Platta på mark av korslimmat trä : En undersökning av bärförmåga med och utan kantförstyvning

    Uppsats för yrkesexamina på grundnivå, Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

    Författare :Linnéa Hellman; Nils Falck; [2021]
    Nyckelord :KL-trä; kantbalk; kantförstyvning; platta på mark; bäddmodul; kontakttryck; FEM-design;

    Sammanfattning : Purpose: This work investigates the load-bearing capacity of a foundation built out of cross-laminated timber. The foundation is built with the same principles as a slab on grade made out of concrete. The purpose is also to account for the different operating principles of a wooden slab on grade with, and without, an edge beam. LÄS MER
