  1. 1. 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

  3. 2. Reinforced Concrete Subjected To Restraint Forces : A comparison with non-linear numerical analyses

    University essay from KTH/Bro- och stålbyggnad

    Author : Niels Brattström; Oliver Hagman; [2017]
    Keywords : Restraint forces; concrete; cracking; restraint degree; crack width; creep; thermal actions; shrinkage; Tvångskrafter; betong; sprickor; inspänningsgrad; sprickvidder; krypning; termisk last; krympning;

    Abstract : In Sweden, it is Eurocode 2 which forms the basis for performing a design of concrete structures, in which methods can be found treating the subject of restrained concrete members and cracking in the serviceability limit state. In the code, both detailed hand calculations procedures as well as simplified methods are described. READ MORE

  4. 3. Design of Thick Concrete Beams : Using Non-Linear FEM

    University essay from KTH/Bro- och stålbyggnad

    Author : Daniel Mekonnen Teklemariam; Bennie Hamunzala; [2016]
    Keywords : Thick concrete beam; Capacity; Non-linear finite element analysis; Crack width; Load deformation response; Ultimate and Serviceability limit state.; Tjocka betongbalkar; Kapacitet; Icke-linjära finita element analys; Sprikvidd; Deformation; Brott-och bruksgränstillstånd;

    Abstract : The experimental studies performed on the behaviour of very thick concrete beams subjected to static loads have revealed that the shear mechanisms play an important role in the overall response and failure behaviour. The aim of this thesis is to recommend suitable design methods for thick concrete beams subjected to off-centre static concentrated load according Eurocode 2 by using non-linear finite element analysis (NLFEA).
