  1. 1. Cracking in a slender concrete slab due to thermal variation

    Master-uppsats, KTH/Betongbyggnad

    Författare :Johan Mattsson; Fredrik Åman; [2019]
    Nyckelord :Concrete slab; Concrete; Finite element analysis; Cracking; Thermal variation; Seasonal temperature; Abaqus; Brigade Plus; Betonggrund; Betong; Finit element analys; Sprickbildning; Termiska laster; Omgivningstemperature; Abaqus; Brigade Plus;

    Sammanfattning : Concrete slabs used in thepulp and paper industries are often situated outdoors, which means that theslabs are exposed to temperature variations due to different weatherconditions. These temperature variations together with operational temperaturesassociated with the manufacturing process, may introduce high temperaturegradients in the concrete. LÄS MER

  2. 2. The effect of pre-stressing location on punching shear capacity of concrete flat slabs

    Master-uppsats, KTH/Betongbyggnad

    Författare :Saeed Vosoughian; [2019]
    Nyckelord :Concrete flat slabs; Concrete damage plasticity model; Eurocode 2; Nonlinear finite element analysis; Punching capacity; Pre-stressing cables;

    Sammanfattning :         Implementing pre-stressing cables is a viable option aiming at controlling deformation and cracking of concrete flat slabs in serviceability limit state. The pre-stressing cables also contribute to punching shear capacity of the slab when they are located in vicinity of the column. LÄS MER

  3. 3. Linear and non-linear FE-analysis of cracking behavior of wing walls in integral bridges

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Avdelningen för Konstruktionsteknik

    Författare :Andreas Ekman; Christoffer Sandin; [2018]
    Nyckelord :Non linear FE-modelling; Concrete Damage Plasticity; Wing wall; Crack propagation; Serviceability Limit State; Slab Frame Bridge; Technology and Engineering;

    Sammanfattning : Wing walls on slab frame integral bridges has traditionally been designed for mainly earth pressure and its self-weight. It has also been designed separately from the rest of the bridge. Traditionally no 3D effects have been considered in the design of the wing walls. LÄS MER

  4. 4. Weight reduction of concrete poles for the Swedish power line grid : Using a Finite Element Model to optimize geometry in relation to load requirements

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

    Författare :Jenny Bülow Angeling; [2017]
    Nyckelord :Keywords: FE-model; Finite Element model; Concrete damage plasticity; Fracture mechanics; Fracture energy; Pole;

    Sammanfattning : Because of an eventual ban of creosote-impregnated products, alternative materials for poles used in the electrical grid are needed. Concrete is one alternative and spun concrete poles have been manufactured for the Swedish grid before. These poles are still in use since the high strength and good functioning. LÄS MER

  5. 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
