  1. 1. Global Analysis of a Tall Timber- Concrete Hybrid Structure Subjected to Wind Load : A Parametric Study of Different Hybrid Solutions

    University essay from KTH/Betongbyggnad

    Author : Clara Youssef; Meriam Basilious; [2022]
    Keywords : ;

    Abstract :   Tall timber structures have received more attention in recent times as building withtimber contributes to environmental benefits in comparison to other building materials.Timber- concrete hybrid structures have become an alternative as previous investigationshave shown that building tall timber buildings implies complexities with regardsto sufficient stiffness and discomfort for occupants.

  3. 2. 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

  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. Climate Change Mitigation Measures of Load-Bearing Structure - A comparison of alternative structural designs using Life Cycle Assessment

    University essay from Lunds universitet/Avdelningen för Konstruktionsteknik

    Abstract : I mars 2015 nådde den globalt genomsnittliga koldioxidhalten 400 ppm för första gången på tre miljoner år. Därför satte den svenska regeringen, år 2017, upp målet att Sverige ska vara klimatneutralt år 2045. 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
