  1. 1. Reinforcement Layout in Concrete Pile Foundations : A study based on non - linear finite element analysis

    Master-uppsats, KTH/Betongbyggnad

    Författare :Mohammad Mustafa Angar; [2020]
    Nyckelord :Pile cap; Nonlinear finite element analysis; ATENA 3D; Reinforcement layout; Strut and tie method; Pålfundament; icke-linjära finita elementmodeller; strut and tie-metoden;

    Sammanfattning : The main topic of this thesis concerns the behavior of concrete pile cap supported by four piles with two varying positions of longitudinal reinforcements. The positions include top of piles and bottom of the pile cap. For this purpose, non-linear finite element models of a pile cap are created using software ATENA 3D. LÄS MER

  3. 2. Punching shear in concrete flat slabs supported on slender edge steel columns

    Master-uppsats, KTH/Betongbyggnad

    Författare :Pasha Jalal; Jose Andres Perez; [2020]
    Nyckelord :Punching shear; ATENA; FEA; precast slab; flat slab; top and foot plate.; Genomstansning; ATENA; FEA; plattbärlag; pelardäck; topp- och fotplåt.;

    Sammanfattning : Punching shear is a failure mechanism caused by concentrated loads, creating a crack pattern that resembles a cone shape or piece of pie starting from the top surface of the slab and prolongs downwards. When the total shear force is greater than the shear resistance of the slab, it may eventually lead to punching shear failure. LÄS MER

  4. 3. FE-analys av sprickvidder i ung betong på grund av tvång

    M1-uppsats, KTH/Byggteknik och design

    Författare :Martin Lagesson; Anton Hägerstrand; [2017]
    Nyckelord :Temperature cracking; Early age concrete; restraint; Finite Element Modelling; Atena; Temperatursprickor; Ung betong; Tvång; FE-modellering; Atena;

    Sammanfattning : Betong är ett av våra idag absolut viktigaste och vanligaste byggnadsmaterial. Betong har väldigt låg draghållfasthet och på grund av detta spricker betongkonstruktioner oftast. Att helt förhindra att betong spricker är svårt och ofta kostsamt istället ställs krav för hur vida sprickorna får vara. LÄS MER

  5. 4. Shear Stiffness and Capacity of Joints Between Precast Wall Elements

    Master-uppsats, KTH/Betongbyggnad

    Författare :Semiha Kaya; Delvin Salim; [2017]
    Nyckelord :Non-linear finite element analysis; prefabricated concrete elements; shear stiffness;

    Sammanfattning : In this thesis an investigation of the shear stiffness and capacity of joints between pre- fabricated concrete elements regarding to different material properties is reported. Two different models of shear key joints, connected to prefabricated walls, were cre- ated in the non-linear finite element software, ATENA 3D, with the aim to estimate a realistic behaviour of the joints regarding to the external loads.

  7. 5. Non-Linear Assessment of a Concrete Bridge Slab Loaded to Failure

    Master-uppsats, KTH/Betongbyggnad

    Författare :Eriksson Isabell; Niklas Karlsson; [2016]
    Nyckelord :concrete; linear shear; punching shear; non-linear finite element analysis; Eurocode; Model Code; ATENA 3D; betong; skjuvning; genomstansning; icke-linjär finit-elementanalys; Eurocode; Model Code; ATENA 3D;

    Sammanfattning : This thesis covers an investigation regarding the failure in the bridge slab of Gruvvägsbron, which was the result of the full scale test that the bridge was subjected to prior to demolition. Using the non-linear finite element software ATENA 3D, a model of the bridge was assembled, with the purpose to attempt to reenact the test procedure and realistically capture the failure load and behaviour.
