1. Reinforcement Layout in Concrete Pile Foundations : A study based on non - linear finite element analysis
Master-uppsats, KTH/BetongbyggnadSammanfattning : The main topic of this thesis concerns the behavior of concrete pile cap supported by four piles with two varying positions of longitudinal reinforcements. The positions include top of piles and bottom of the pile cap. For this purpose, non-linear finite element models of a pile cap are created using software ATENA 3D. LÄS MER
2. Punching shear in concrete flat slabs supported on slender edge steel columns
Master-uppsats, KTH/BetongbyggnadSammanfattning : Punching shear is a failure mechanism caused by concentrated loads, creating a crack pattern that resembles a cone shape or piece of pie starting from the top surface of the slab and prolongs downwards. When the total shear force is greater than the shear resistance of the slab, it may eventually lead to punching shear failure. LÄS MER
3. FE-analys av sprickvidder i ung betong på grund av tvång
M1-uppsats, KTH/Byggteknik och designSammanfattning : Betong är ett av våra idag absolut viktigaste och vanligaste byggnadsmaterial. Betong har väldigt låg draghållfasthet och på grund av detta spricker betongkonstruktioner oftast. Att helt förhindra att betong spricker är svårt och ofta kostsamt istället ställs krav för hur vida sprickorna får vara. LÄS MER
4. Shear Stiffness and Capacity of Joints Between Precast Wall Elements
Master-uppsats, KTH/BetongbyggnadSammanfattning : In this thesis an investigation of the shear stiffness and capacity of joints between pre- fabricated concrete elements regarding to different material properties is reported. Two different models of shear key joints, connected to prefabricated walls, were cre- ated in the non-linear finite element software, ATENA 3D, with the aim to estimate a realistic behaviour of the joints regarding to the external loads.

5. Non-Linear Assessment of a Concrete Bridge Slab Loaded to Failure
Master-uppsats, KTH/BetongbyggnadSammanfattning : This thesis covers an investigation regarding the failure in the bridge slab of Gruvvägsbron, which was the result of the full scale test that the bridge was subjected to prior to demolition. Using the non-linear finite element software ATENA 3D, a model of the bridge was assembled, with the purpose to attempt to reenact the test procedure and realistically capture the failure load and behaviour.
