1. Numerical study of the effect of thermal ice loads on concrete dams
Master-uppsats, KTH/BetongbyggnadSammanfattning : 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. LÄS MER
2. Thermal cracking of a concrete arch dam due to seasonal temperature variations
Master-uppsats, KTH/BetongbyggnadSammanfattning : Concrete dams located in northern regions are exposed to large seasonal temperature variations. These seasonal temperature variations have resulted in cracking in thin concrete dams. Continuous monitoring and evaluation of existing dams are important to increase the knowledge about massive concrete structures and to ensure dam safety. LÄS MER
3. Finite element analysis of cracking of concrete arch dams due to seasonal temperature variation
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaperSammanfattning : Flera dammkonstruktioner i Norden utsätts för stora temperaturvariationer mellan sommar och vinter. I norra Sverige kan dammar vara utsatta för temperaturvariationer på upp emot 60–70 °C. Detta resulterar ofta i sprickbildning i betongen vilket medför utmaningar vid både utformning av nya dammar och underhåll av befintliga. LÄS MER
4. Verification of the response of a concrete arch dam subjected to seasonal temperature variations
Master-uppsats, KTH/BetongbyggnadSammanfattning : Many dams existing today were constructed around fifty years ago. Condition monitoring is essential for maintaining high safety and determining the current level of safety and stability for these dams. There is a need for new monitoring techniques and finite element coupled monitoring could be one of these techniques. LÄS MER
5. Influence of Fluid Structure Interaction on a Concrete Dam during Seismic Excitation : -Parametric analyses of an Arch Dam-Reservoir-Foundation system
Master-uppsats, KTH/BetongbyggnadSammanfattning : The aim of this study is to investigate how Fluid-Structure interaction is included in numerical earthquake analyses of dams. The base for this project is theme A from the 12th international benchmark workshop on numerical analysis of dams, which was held in October 2013. LÄS MER
