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

    University essay from KTH/Bro- och stålbyggnad

    Author : Evelina Husak; Ellinor Persson; [2022]
    Keywords : ;

    Abstract : 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. READ MORE

  3. 2. Reinforced Concrete Structures Subjected to Imposed Deformations: A Study of Cracking due to Shrinkage in Slab Foundations for Residential Houses

    University essay from Lunds universitet/Avdelningen för Konstruktionsteknik; Lunds universitet/Institutionen för bygg- och miljöteknologi

    Author : Henrik Johansson; Martin Heinegård; [2020]
    Keywords : Reinforced concrete structures; nonlinear finite element analysis; crack widths; imposed deformations; shrinkage; foundation slabs; fracture mechanics; Atena 2D; Technology and Engineering;

    Abstract : The need for limiting crack widths in reinforced concrete structures is due to durability, tightness towards gaseous and liquid substances, and for aesthetic reasons. Although concrete cracks at relatively low tensile stresses and can not be avoided, strategies for crack control can be adopted to meet the requirements. READ MORE

  4. 3. The impact of stage casting on shrinkage restraint in concrete walls

    University essay from KTH/Byggteknik och design

    Author : Cindy Amjadi; Justyna Melek; [2020]
    Keywords : Concrete; concrete wall; stage casting; shrinkage restraint; cracking; FEM-Design; Betong; betongvägg; gjutetappindelning; krymptvång; sprickor; FEM-Design;

    Abstract : The most used widely material in the construction and industrial industry is concrete. Concrete is a material that has been used for a long time and will remain to do so. Therefore, it is especially important to obtain knowledge of the material’s properties and how it is affected by various conditions. READ MORE

  5. 4. Freeze-drying of protein pharmaceuticalin vials with different character

    University essay from Uppsala universitet/Institutionen för farmaci

    Author : Julia Falk; [2019]
    Keywords : ;

    Abstract : Freeze-drying of protein pharmaceuticals is a procedure frequentlyused to obtain stability of the active pharmaceutical ingredientduring distribution and storage. It can be performed in pre-filledsyringes, with a lubricous coating of silicone on the inside, toenable the piston moving. READ MORE

  6. 5. Study of crack width within a suspended concrete slab with different amount of cement clinker considering lower climate impact

    University essay from KTH/Betongbyggnad

    Author : Sedige Feizi; Fateha Yasmin Khan; [2018]
    Keywords : concrete; lower climate impact; carbon dioxide emission; cement clinker; fly ash; laboratory test; slab; crack width; analytical calculation; FEM-design; betong; lägre klimatpåverkan; koldioxidutsläpp; exponering klass; cementklinker; flygaska; laboratorium; platta; sprickvidd; analytisk beräkning; FEM-design;

    Abstract : This master thesis investigates the possibility of using a concrete recipe with only 70 % cement clinker for a building project named Gretas Glänta, regarding the demands of cracking for a suspended slab. The requirement to fulfill was a maximum crack width of 0.2 mm due to drying shrinkage and long- term loading. READ MORE
