    Sammanfattning : This report formulates the boundary conditions and discretization method for conducting a simulation of heat with liquids and solids through the finite element method. It introduces the reader to the movement that is due today with optimization of heat transport and mitigation generally described as the fourth generation of district heating. LÄS MER

  2. 2. Shear Failure of Steel Fiber and Bar Reinforced Concrete Beams Without Stirrups : Predictions based on Nonlinear Finite Element Analyses

    Master-uppsats, KTH/Betongbyggnad

    Författare :David Andersson; [2022]
    Nyckelord :Nonlinear finite element analysis; Shear failure; Fiber reinforced concrete beams; ATENA;

    Sammanfattning : Shear failure in concrete beams are often brittle in nature and potentially dangerous without adequatereinforcing measures. In design of concrete, it is commonly recommended to install transversalreinforcement along the shear span to induce a more ductile structural response, improving the shearcapacity all together and providing sufficient warning prior to collapse.

  3. 3. Simulation of load capacity of 3D printed concrete patterns

    Master-uppsats, KTH/Betongbyggnad

    Författare :Magnus Burton; Karolina Näsén; [2022]
    Nyckelord :;

    Sammanfattning : Three-dimensional concrete printing (3DCP) is a technology which has rapidly developed in recent years. The technology is based on a layer-by-layer technique where models are designed in a 3D software program and printed by a robot. Unlike conventional concrete, 3DCP has stricter material requirements due to the absence of formwork. LÄS MER

  4. 4. Numerical method to investigate and assess the capacity of a damaged concrete structure : Using image analysis and advanced concrete modeling

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :Zakariya Benosmane; [2022]
    Nyckelord :Damaged Concrete Structure; Extended Finite Element Method XFEM ; Concrete Dam- aged Plasticity CDP ; Photogrammetry; Crack Detection Methods.;

    Sammanfattning : Concrete has for decades been one of the main materials used to construct important structuressuch as dams and bridges. However, after years of service, the concrete structuresstart deteriorating and signs of damages start showing on the structure. LÄS MER

  5. 5. 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
