  1. 1. 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

  2. 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

  3. 3. Redistribution of bending moments in concrete slabs in the SLS

    University essay from KTH/Bro- och stålbyggnad

    Author : Einar Óskarsson; [2014]
    Keywords : Finite element analysis; reinforced concrete; concrete slab; non-linear analysis; crack control; fracture energy;

    Abstract : The finite element method (FEM) is commonly used to design the reinforcement in concrete slabs. In order to simplify the analysis and to be able to utilize the superposition principle for evaluating the effect of load combinations, a linear analysis is generally adopted although concrete slabs normally have a pronounced non-linear response.
