  1. 11. Numerical study of the effect of thermal ice loads on concrete dams

    University essay from KTH/Betongbyggnad

    Author : Imal Zuwak; Wasseem Kordoghly; [2020]
    Keywords : Arch dam; Buttress dam; Concrete; Finite element analysis; Ice load; Valvdamm; Lamelldamm; Betong; Finit elementanalys; Islast;

    Abstract : It is essential to understand the mechanics of ice load and how it affects concrete dams located in a cold climate, such as Sweden, where the temperature becomes sufficiently cold to freeze the surface of the reservoir. The purpose of this thesis is to study ice load distribution along concrete dams, and its response during the application of an ice load. READ MORE

  3. 12. 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. 13. The effect of pre-stressing location on punching shear capacity of concrete flat slabs

    University essay from KTH/Betongbyggnad

    Author : Saeed Vosoughian; [2019]
    Keywords : Concrete flat slabs; Concrete damage plasticity model; Eurocode 2; Nonlinear finite element analysis; Punching capacity; Pre-stressing cables;

    Abstract :         Implementing pre-stressing cables is a viable option aiming at controlling deformation and cracking of concrete flat slabs in serviceability limit state. The pre-stressing cables also contribute to punching shear capacity of the slab when they are located in vicinity of the column. READ MORE

  5. 14. Nonlinear Modelling and Simulation of Impact Events and Validation with Experimental Test

    University essay from KTH/Lättkonstruktioner

    Author : András Péter Székely; Nicole Al Hanna; [2019]
    Keywords : ;

    Abstract : For rattle event prediction accurate models capable of estimating system response at impact are required. In this thesis, a finite element model is built to imitate a physical setup designed for testing rattle. First, a modal analysis is performed in ABAQUS/Standard to validate the CAE model. READ MORE

  6. 15. A stable and accurate hybrid FE-FD method

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Tuan Anh Dao; [2019]
    Keywords : ;

    Abstract : We develop a hybrid method to couple finite difference methods and finite element methods in a nonconforming multiblock fashion. The aim is to optimize computational efficiency when complex geometries present. READ MORE
