  1. 1. Concrete in vertical slipforms : A process for determining a suitable concrete composition

    Master-uppsats, KTH/Betongbyggnad

    Författare :Ellen Gegerfelt; Alva Hasselqvist; [2021]
    Nyckelord :Slipforming; fresh concrete; workability; consistency; alternative binders; slipform rate; lifting cracks; delamination; lump formation; Glidformsgjutning; färsk betong; arbetbarhet; konsistens; alternativa bindemedel; glidformshastighet; lyftsprickor; delaminering; klumpbildning;

    Sammanfattning : In the construction industry of today, many projects are getting bigger, higher and more complicated than ever before. The most important material in these projects is concrete and the process of casting has developed a lot during the last century. LÄS MER

  3. 2. Evaluate Machine Learning Model to Better Understand Cutting in Wood

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Md Tahseen Anam; [2021]
    Nyckelord :Machine Learning; Mask R-CNN; Image Analysis; Wood Image; Pith Detection; Knots; Cracks; Cutting Efficiency;

    Sammanfattning : Wood cutting properties for the chains of chainsaw is measured in the lab by analyzing the force, torque, consumed power and other aspects of the chain as it cuts through the wood log. One of the essential properties of the chains is the cutting efficiency which is the measured cutting surface per the power used for cutting per the time unit. LÄS MER

  4. 3. Modelling and simulations of window attachments for a surface warfare ship

    Master-uppsats, KTH/Flygdynamik

    Författare :Mohammad Mekdadi; [2020]
    Nyckelord :;

    Sammanfattning : In recent years it has been discovered that the window installations on the Visby class corvette are prone to break. The aim of this report is to perform a structural analysis of three different windowinstallations. LÄS MER

  5. 4. Nonlinear Finite Element Analysis of Shrinking Reinforced Concrete Slabs-on-ground

    Master-uppsats, KTH/Betongbyggnad

    Författare :Shruthi Prakash; [2018]
    Nyckelord :Slabs-on-ground; Gradient shrinkage; Statical indeterminate structure; Vertical deflection and Cracking;

    Sammanfattning : Concrete slabs-on-ground are commonly used in many types of industrial floors, warehouses, highways, parking lots and buildings. Cracks and deflection of slabs are undesired events caused by differential shrinkage, which limits the service life of the slabs. LÄS MER

  7. 5. Nonlinear analysis of reinforced concrete slab on partially softening ground : Ickelinjär analys av armerad betongplatta på delvis uppmjuknande grund

    Master-uppsats, KTH/Betongbyggnad

    Författare :Yang Zhou; [2017]
    Nyckelord :Reinforced concrete slab foundation; Nonlinear analysis; FEM;

    Sammanfattning : Reinforced concrete slabs are a conventional type of foundation that is widely used in residential, commercial and industrial buildings. Most of the slab foundations are constructed directly on the ground without another structural medium in between and some of the slabs are therefore influenced by ground softening. LÄS MER
